+Migrating from MySQL/MariaDB to PostgreSQL
+==========================================
+
+Our recommended database for all production installations is PostgreSQL. Support for MySQL/MariaDB will be removed in
+pretix 5.0.
+
+In order to follow this guide, your pretix installation needs to be a version that fully supports MySQL/MariaDB. If you
+already upgraded to pretix 5.0, downgrade back to the last 4.x release using ``pip``.
+
+.. note:: We have tested this guide carefully, but we can't assume any liability for its correctness. The data loss
+          risk should be low as long as pretix is not running while you do the migration. If you are a pretix Enterprise
+          customer, feel free to reach out in advance if you want us to support you along the way.
+
+Update database schema
+----------------------
+
+Before you start, make sure your database schema is up to date::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+Install PostgreSQL
+------------------
+
+Now, install and set up a PostgreSQL server. For a local installation on Debian or Ubuntu, use::
+
+    # apt install postgresql
+
+Having the database server installed, we still need a database and a database user. We can create these with any kind
+of database managing tool or directly on our database's shell. Please make sure that UTF8 is used as encoding for the
+best compatibility. You can check this with the following command::
+
+    # sudo -u postgres psql -c 'SHOW SERVER_ENCODING'
+
+Without Docker
+""""""""""""""
+
+For our standard manual installation, create the database and user like this::
+
+    # sudo -u postgres createuser pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+With Docker
+"""""""""""
+
+For our standard docker installation, create the database and user like this::
+
+    # sudo -u postgres createuser -P pretix
+    # sudo -u postgres createdb -O pretix pretix
+
+Make sure that your database listens on the network. If PostgreSQL on the same same host as docker, but not inside a docker container, we recommend that you listen on the Docker interface by changing the following line in ``/etc/postgresql/<version>/main/postgresql.conf``::
+
+    listen_addresses = 'localhost,172.17.0.1'
+
+You also need to add a new line to ``/etc/postgresql/<version>/main/pg_hba.conf`` to allow network connections to this user and database::
+
+    host    pretix          pretix          172.17.0.1/16           md5
+
+Restart PostgreSQL after you changed these files::
+
+    # systemctl restart postgresql
+
+If you have a firewall running, you should also make sure that port 5432 is reachable from the ``172.17.0.1/16`` subnet.
+
+Of course, instead of all this you can also run a PostgreSQL docker container and link it to the pretix container.
+
+Stop pretix
+-----------
+
+To prevent any more changes to your data, stop pretix from running::
+
+    # systemctl stop pretix-web pretix-worker
+
+Change configuration
+--------------------
+
+Change the database configuration in your ``/etc/pretix/pretix.cfg`` file::
+
+    [database]
+    backend=postgresql
+    name=pretix
+    user=pretix
+    password=  ; only required for docker or remote database, can be kept empty for local auth
+    host=      ; set to 172.17.0.1 in docker setup, keep empty for local auth
+
+
+Create database schema
+-----------------------
+
+To create the schema in your new PostgreSQL database, use the following commands::
+
+    # sudo -u pretix -s
+    $ source /var/pretix/venv/bin/activate
+    (venv)$ python -m pretix migrate
+
+
+Migrate your data
+-----------------
+
+Install ``pgloader``::
+
+    # apt install pgloader
+
+.. note::
+
+   If you are using Ubuntu 20.04, the ``pgloader`` version from the repositories seems to be incompatible with PostgreSQL
+   12+. You can install ``pgloader`` from the `PostgreSQL repositories`_ instead.
+   See also `this discussion <https://github.com/pretix/pretix/issues/3090>`_.
+
+Create a new file ``/tmp/pretix.load``, replacing the MySQL and PostgreSQL connection strings with the correct user names, passwords, and/or database names::
+
+    LOAD DATABASE
+        FROM mysql://pretix:password@localhost/pretix  -- replace with mysql://username:password@hostname/dbname
+        INTO postgresql:///pretix                      -- replace with dbname
+
+    WITH data only, include no drop, truncate, disable triggers,
+         create no indexes, drop indexes, reset sequences
+
+    ALTER SCHEMA 'pretix' RENAME TO 'public'           -- replace pretix with the name of the MySQL database
+
+    ALTER TABLE NAMES MATCHING ~/.*/
+        SET SCHEMA 'public'
+
+    SET timezone TO '+00:00'
+
+    SET PostgreSQL PARAMETERS
+         maintenance_work_mem to '128MB',
+         work_mem to '12MB';
+
+Then, run::
+
+    # sudo -u postgres pgloader /tmp/pretix.load
+
+The output should end with a table summarizing the results for every table. You can ignore warnings about type casts
+and missing constraints.
+
+Afterwards, delete the file again::
+
+    # rm -rf /tmp/pretix.load
+
+Start pretix
+------------
+
+Now, restart pretix. Maybe stop your MySQL server as a verification step that you are no longer using it::
+
+    # systemctl stop mariadb
+    # systemctl start pretix-web pretix-worker
+
+And you're done! After you've verified everything has been copied correctly, you can delete the old MySQL database.
+
+.. note:: Don't forget to update your backup process to back up your PostgreSQL database instead of your MySQL database now.
+
+Troubleshooting
+---------------
+
+Peer authentication failed
+""""""""""""""""""""""""""
+
+Sometimes you might see an error message like this::
+
+    django.db.utils.OperationalError: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  Peer authentication failed for user "pretix"
+
+It is important to understand that PostgreSQL by default offers two types of authentication:
+
+- **Peer authentication**, which works automatically based on the Linux user you are working as. This requires that
+  the connection is made through a local socket (empty ``host=`` in ``pretix.cfg``) and the name of the PostgreSQL user
+  and the Linux user are identical.
+
+  - Typically, you might run into this error if you accidentally execute ``python -m pretix`` commands as root instead
+    of the ``pretix`` user.
+
+- **Password authentication**, which requires a username and password and works over network connections. To force
+  password authentication instead of peer authentication, set ``host=127.0.0.1`` in ``pretix.cfg``.
+
+  - You can alter the password on a PostgreSQL shell using the command ``ALTER USER pretix WITH PASSWORD '***';``.
+    When creating a user with the ``createuser`` command, pass option ``-P`` to set a new password.
+
+  - Even with password authentication, PostgreSQL by default only allows local connections. To allow remote connections,
+    you need to adjust both the ``listen_address`` configuration parameter as well as the ``pg_hba.conf`` file (see above
+    for an example with the docker networking setup).
+
+Database error: relation does not exist
+"""""""""""""""""""""""""""""""""""""""
+
+If you see an error like this::
+
+    2023-04-17T19:20:47.744023Z ERROR Database error 42P01: relation "public.pretix_foobar" does not exist
+    QUERY: ALTER TABLE public.pretix_foobar DROP CONSTRAINT IF EXISTS pretix_foobar_order_id_57e2cb41_fk_pretixbas CASCADE;
+    2023-04-17T19:20:47.744023Z FATAL Failed to create the schema, see above.
+
+The reason is most likely that in the past, you installed a pretix plugin that you no longer have installed. However,
+the database still contains tables of that plugin. If you want to keep the data, reinstall the plugin and re-run the
+``migrate`` step from above. If you want to get rid of the data, manually drop the table mentioned in the error message
+from your MySQL database::
+
+    # mysql -u root pretix
+    mysql> DROP TABLE pretix_foobar;
+
+Then, retry. You might see a new error message with a new table, which you can handle the same way.
+
+Cleaning out a failed attempt
+"""""""""""""""""""""""""""""
+
+You might want to clean your PostgreSQL database before you try again after an error. You can do so like this::
+
+    # sudo -u postgres psql pretix
+    pretix=# DROP SCHEMA public CASCADE;
+    pretix=# CREATE SCHEMA public;
+    pretix=# ALTER SCHEMA public OWNER TO pretix;
+
+``pgloader`` crashes with heap exhaustion error
+"""""""""""""""""""""""""""""""""""""""""""""""
+
+On some larger databases, we've seen ``pgloader`` crash with error messages similar to this::
+
+    Heap exhausted during garbage collection: 16 bytes available, 48 requested.
+
+Or this::
+
+    2021-01-04T21:31:17.367000Z ERROR A SB-KERNEL::HEAP-EXHAUSTED-ERROR condition without bindings for heap statistics.  (If
+    you did not expect to see this message, please report it.
+    2021-01-04T21:31:17.382000Z ERROR The value
+      NIL
+    is not of type
+      NUMBER
+    when binding SB-KERNEL::X
+
+The ``pgloader`` version distributed for Debian and Ubuntu is compiled with the ``SBCL`` compiler. If compiled with
+``CCL``, these bugs go away. Unfortunately, it is pretty hard to compile ``pgloader`` manually with ``CCL``. If you
+run into this, we therefore recommend using the docker container provided by the ``pgloader`` maintainers::
+
+    sudo docker run --rm -v /tmp:/tmp --network host -it dimitri/pgloader:ccl.latest pgloader /tmp/pretix.load
+
+As peer authentication is not available from inside the container, this requires you to use password-based authentication
+in PostgreSQL (see above).

-We currently see pretix' API as a beta-stage feature. We therefore do not give any guarantees
-for compatibility between feature releases of pretix (such as 1.5 and 1.6). However, as always,
-we try not to break things when we don't need to. Any backwards-incompatible changes will be
-prominently noted in the release notes.
+We try to avoid any breaking changes to our API to avoid hassle on your end. If possible, we'll
+build new features in a way that keeps all pre-existing API usage unchanged. In some cases,
+this might not be possible or only possible with restrictions. In these case, any
+backwards-incompatible changes will be prominently noted in the "Changes to the REST API"
+section of our release notes. If possible, we will announce them multiple releases in advance.

+--------------------
+
+.. http:post:: /api/v1/organizers/(organizer)/checkinrpc/redeem/
+
+   Tries to redeem an order position, i.e. checks the attendee in (or out). This is the recommended endpoint to use
+   if you build any kind of scanning app that performs check-ins for scanned barcodes. It is safe to use with untrusted
+   inputs in the ``secret`` field.
+
+   This endpoint supports passing multiple check-in lists to perform a multi-event scan. However, each check-in list
+   passed needs to be from a distinct event.
+
+   :<json string secret: Scanned QR code corresponding to the ``secret`` attribute of a ticket.
+   :<json string source_type: Type of source the ``secret`` was obtained form. Defaults to ``"barcode"``.
+   :<json array lists: List of check-in list IDs to search on. No two check-in lists may be from the same event.
+   :<json string type: Send ``"exit"`` for an exit and ``"entry"`` (default) for an entry.
+   :<json datetime datetime: Specifies the datetime of the check-in. If not supplied, the current time will be used.
+   :<json boolean force: Specifies that the check-in should succeed regardless of revoked barcode, previous check-ins or required
+                         questions that have not been filled. This is usually used to upload offline scans that already happened,
+                         because there's no point in validating them since they happened whether they are valid or not. Defaults to ``false``.
+   :<json boolean questions_supported: When this parameter is set to ``true``, handling of questions is supported. If
+                                       you do not implement question handling in your user interface, you **must**
+                                       set this to ``false``. In that case, questions will just be ignored. Defaults
+                                       to ``true``.
+   :<json boolean ignore_unpaid: Specifies that the check-in should succeed even if the order is in pending state.
+                                 Defaults to ``false`` and only works when ``include_pending`` is set on the check-in
+                                 list.
+   :<json object answers: If questions are supported/required, you may/must supply a mapping of question IDs to their
+                          respective answers. The answers should always be strings. In case of (multiple-)choice-type
+                          answers, the string should contain the (comma-separated) IDs of the selected options.
+   :<json string nonce: You can set this parameter to a unique random value to identify this check-in. If you're sending
+                        this request twice with the same nonce, the second request will also succeed but will always
+                        create only one check-in object even when the previous request was successful as well. This
+                        allows for a certain level of idempotency and enables you to re-try after a connection failure.
+   :>json string status: ``"ok"``, ``"incomplete"``, or ``"error"``
+   :>json string reason: Reason code, only set on status ``"error"``, see below for possible values.
+   :>json string reason_explanation: Human-readable explanation, only set on status ``"error"`` and reason ``"rules"``, can be null.
+   :>json object position: Copy of the matching order position (if any was found). The contents are the same as the
+                           :ref:`order-position-resource`, with the following differences: (1) The ``checkins`` value
+                           will only include check-ins for the selected list. (2) An additional boolean property
+                           ``require_attention`` will inform you whether either the order or the item have the
+                           ``checkin_attention`` flag set. (3) If ``attendee_name`` is empty, it may automatically fall
+                           back to values from a parent product or from invoice addresses.
+   :>json boolean require_attention: Whether or not the ``require_attention`` flag is set on the item or order.
+   :>json object list: Excerpt of information about the matching :ref:`check-in list <rest-checkinlists>` (if any was found),

+Performing a ticket search
+--------------------------
+
+.. http:get:: /api/v1/organizers/(organizer)/checkinrpc/search/
+
+   Returns a list of all order positions matching a given search request. The result is the same as
+   the :ref:`order-position-resource`, with the following differences:
+
+   * The ``checkins`` value will only include check-ins for the selected list.
+
+   * An additional boolean property ``require_attention`` will inform you whether either the order or the item
+     have the ``checkin_attention`` flag set.
+
+   * If ``attendee_name`` is empty, it will automatically fall back to values from a parent product or from invoice
+     addresses.
+
+   This endpoint supports passing multiple check-in lists to perform a multi-event search. However, each check-in list
+   passed needs to be from a distinct event.
+
+   **Example request**:
+

+Data shredders
+==============
+
+pretix and it's plugins include a number of data shredders that allow you to clear personal information from the system.
+This page shows you how to use these shredders through the API.
+
+.. versionchanged:: 4.12
+
+   This feature has been added to the API.
+
+.. warning::
+
+   Unlike the user interface, the API will not force you to download tax-relevant data before you delete it.
+

+
+Running an export
+-----------------
+
+Before you can delete data, you need to start a data export.
+Since exports often include large data sets, they might take longer than the duration of an HTTP request. Therefore,
+creating an export is a two-step process. First you need to start an export task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/shredders/export/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to the download URL of the result as well as the URL for the next step.
+
+   **Example request**:
+
+   .. sourcecode:: http
+
+      POST /api/v1/organizers/bigevents/events/sampleconf/shredders/export/ HTTP/1.1
+      Host: pretix.eu

+      }
+
+   :param organizer: The ``slug`` field of the organizer to fetch
+   :param event: The ``slug`` field of the event to fetch
+   :param identifier: The ``identifier`` field of the exporter to run
+   :statuscode 202: no error

+   :statuscode 401: Authentication failure
+   :statuscode 403: The requested organizer/event does not exist **or** you have no permission to view this resource.
+
+
+Downloading the result
+----------------------
+
+When starting an export, you receive a ``download`` URL for downloading the result. Running a ``GET`` request on that result will
+yield one of the following status codes:
+
+* ``200 OK`` – The export succeeded. The body will be your resulting file. Might be large!
+* ``409 Conflict`` – Your export is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+* ``404 Not Found`` – The export does not exist / is expired / belongs to a different API key.
+
+
+Shredding the data
+------------------
+
+When starting an export, you receive a ``shred`` URL for actually shredding the data.
+You can only start the actual shredding process after the export file was generated, however you are not forced to download
+the file (we'd recommend it in most cases, though).
+The download will no longer be possible after the shredding.
+Since shredding often requires deleting large data sets, it might take longer than the duration of an HTTP request.
+Therefore, shredding again is a two-step process. First you need to start a shredder task with one of the following to API
+endpoints:
+
+.. http:post:: /api/v1/organizers/(organizer)/events/(event)/shredders/shred/(id1)/(id2)/
+
+   Starts an export task. If your input parameters validate correctly, a ``202 Accepted`` status code is returned.
+   The body points you to an URL you can use to check the status.

+
+   .. sourcecode:: http

+   :statuscode 410: Either the job has timed out or running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``
+
+
+Checking the result
+-------------------
+
+When starting to shred, you receive a ``status`` URL for checking for success.
+Running a ``GET`` request on that result will yield one of the following status codes:
+
+* ``200 OK`` – The shredding succeeded.
+* ``409 Conflict`` – Shredding is still running. The body will be JSON with the structure ``{"status": "running"}``. ``status`` can be ``waiting`` before the task is actually being processed. Please retry, but wait at least one second before you do.
+* ``410 Gone`` – We no longer know about this process, probably the process was started more than an hour ago. Might also occur after successful operations on small pretix installations without asynchronous task handling.
+* ``417 Expectation Failed`` – Running the export has failed permanently. The body will be JSON with the structure ``{"status": "failed", "message": "Error message"}``

+Customer accounts
+=================
+
+By default, pretix only offers guest checkout, i.e. ticket buyers do not sign up and sign back in, but create a new
+checkout session every time. In some situations it may be convenient to allow ticket buyers to create
+accounts that they can later log in to again. Working with customer accounts is even required for some advanced
+use cases such as described in the :ref:`seasontickets` article.
+
+Enabling customer accounts
+--------------------------
+
+To enable customer accounts, head to your organizer page in the backend and then select "Settings" → "General" →
+"Customer accounts" and turn on the checkbox "Allow customers to create accounts".
+
+Using the other settings on the same tab you can fine-tune how the customer account system behaves:
+
+.. thumbnail:: ../../screens/organizer/edit_customer.png
+   :align: center
+   :class: screenshot
+
+Allow customers to log in with email address and password
+    In all simple setups, this option should be checked. If this checkbox is removed, it is impossible to log in or
+    sign up unless you connect a SSO provider (see below).
+
+Match orders based on email address
+    If this option is selected, customers will see orders made with their email address within their account even if
+    they did not make those orders while logged in.
+
+Name format, Allowed titles
+    This controls how we'll ask your customers for their name, similar to the respective settings on event level.
+
+Managing customer accounts
+--------------------------
+
+After customer accounts have been enabled, you will find a new menu option "Customer accounts" in the organizer-level
+main menu. The first sub-item, "Customers", allows you to search and inspect the list of your customer accounts, as well
+as to create a new customer account from the backend:
+
+.. thumbnail:: ../../screens/organizer/customers.png
+   :align: center
+   :class: screenshot
+
+If you click on a customer ID, you can see all details of this customer account, including registration information,
+active memberships, past ticket orders, and account history:
+
+.. thumbnail:: ../../screens/organizer/customer.png
+   :align: center
+   :class: screenshot
+
+You can also perform various actions from this view, such as:

+- Send a password reset link
+- Change registration information
+- Anonymize the customer account (does not anonymize connected orders)
+
+When creating or changing a customer, you will be presented with the following form:
+
+.. thumbnail:: ../../screens/organizer/customer_edit.png
+   :align: center
+   :class: screenshot
+
+Most fields, such as name, e-mail address, phone number, and language should be self-explanatory. The following fields
+might require some explanation:
+
+Account active
+    If this checkbox is removed, the customer will not be able to log in.
+
+External identifier
+    This field can be used to cross-reference your customer database with other sources. For example, if the customer
+    already has a number in another system, you can insert that number here. This can be especially powerful if you
+    use our API for synchronization with an external system.
+
+Verified email address
+    This checkbox signifies whether you have verified that this customer in fact controls the given email address.
+    This will automatically be checked after a successful registration or after a successful password reset. Before it
+    is checked, the customer will not be able to log in. You should usually not modify this field manually.
+
+Notes
+    Entries in this field will only be visible to you and your team, not to the customer.
+
+Single-Sign-On (SSO)
+--------------------
+
+"Single-Sign-On" (SSO) is a technical term for a situation in which a person can log in to multiple systems using just
+one login. This can be convenient if you have multiple applications that are exposed to your customers: They won't have
+to remember multiple passwords or understand how your application landscape is structured, they can just always log in
+with the same credentials whenever they see your brand.
+
+In this scenario, pretix can be **either** the "SSO provider" **or** the "SSO client".
+If pretix is the SSO provider, pretix will be the central source of truth for your customer accounts and your other
+applications can connect to pretix to use pretix's login functionality.
+If pretix is the SSO client, one of your existing systems will be the source of truth for the customer accounts and
+pretix will use that system's login functionality.
+
+All SSO support for customer accounts in pretix is currently built on the `OpenID Connect`_ standard, a modern and
+widely accepted standard for SSO in all industries.
+
+Connecting SSO clients (pretix as the SSO provider)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To connect an external application as a SSO client, go to "Customer accounts" → "SSO clients" → "Create a new SSO client"
+in your organizer account.
+
+.. thumbnail:: ../../screens/organizer/customer_ssoclient_add.png
+   :align: center
+   :class: screenshot
+
+You will need to fill out the following fields:
+
+Active
+    If this checkbox is removed, the SSO client can not be used.
+
+Application name
+    The name of your external application, e.g. "digital event marketplace".
+
+Client type
+    For a server-side application which is able to store a secret that will be inaccessible to end users, chose
+    "confidential". For a client-side application, such as many mobile apps, choose "public".
+
+Grant type
+    This value depends on the OpenID Connect implementation of your software.
+
+Redirection URIs
+    One or multiple URIs that the user might be redirected to after the successful or failed login.
+
+Allowed access scopes
+    The types of data the SSO client may access about the customer.
+
+After you submitted all data, you will receive a client ID as well as a client secret. The client secret is shown
+in the green success message and will only ever be shown once. If you need it again, use the option "Invalidate old
+client secret and generate a new one".
+
+You will need the client ID and client secret to configure your external application. The application will also likely
+need some other information from you, such as your **issuer URI**. If you use pretix Hosted and your organizer account
+does not have a custom domain, your issuer will be ``https://pretix.eu/myorgname``, where ``myorgname`` is the short
+form of your organizer account. If you use a custom domain, such as ``tickets.mycompany.net``, then your issuer will be
+``https://tickets.mycompany.net``.
+
+Technical details
+"""""""""""""""""
+
+We implement `OpenID Connect Core 1.0`_, except for some optional parts that do not make sense for pretix or bring no
+additional value. For example, we do not currently support encrypted tokens, offline access, refresh tokens, or passing
+request parameters as JWTs.
+
+We implement the provider metadata section from `OpenID Connect Discovery 1.0`_. You can find the endpoint relative
+to the issuer URI as described above, for example ``http://pretix.eu/demo/.well-known/openid-configuration``.
+
+We implement all three OpenID Connect Core flows:
+
+- Authorization Code Flow (response type ``code``)
+- Implicit Flow (response types ``id_token token`` and ``id_token``)
+- Hybrid Flow (response types ``code id_token``, ``code id_token token``, and ``code token``)
+
+We implement the response modes ``query`` and ``fragment``.
+
+We currently offer the following scopes: ``openid``, ``profile``, ``email``, ``phone``
+
+As well as the following standardized claims: ``iss``, ``aud``, ``exp``, ``iat``, ``auth_time``, ``nonce``, ``c_hash``,
+``at_hash``, ``sub``, ``locale``, ``name``, ``given_name``, ``family_name``, ``middle_name``, ``nickname``, ``email``,
+``email_verified``, ``phone_number``.
+
+The various endpoints are located relative to the issuer URI as described above:
+
+- Authorization: ``<issuer>/oauth2/v1/authorize``
+- Token: ``<issuer>/oauth2/v1/token``
+- User info: ``<issuer>/oauth2/v1/userinfo``
+- Keys: ``<issuer>/oauth2/v1/keys``
+
+We currently do not reproduce their documentation here as they follow the OpenID Connect and OAuth specifications
+without any special behavior.
+
+Connecting SSO providers (pretix as the SSO client)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To connect an external application as a SSO client, go to "Customer accounts" → "SSO providers" → "Create a new SSO provider"
+in your organizer account.
+
+.. thumbnail:: ../../screens/organizer/customer_ssoprovider_add.png
+   :align: center
+   :class: screenshot
+
+The "Provider name" and "Login button label" is what we'll use to show the new login option to the user. For the actual
+connection, we will require information such as the issuer URL, client ID, client secret, scope, and field (or claim)
+names that you will receive from your SSO provider.
+
+.. note::
+
+   If you want your customers to *only* use your SSO provider, it makes sense to turn off the "Allow customers to log in
+   with email address and password" settings option (see above).
+
+Technical details
+"""""""""""""""""
+
+We assume that SSO providers fulfill the following requirements:
+
+- Implementation according to `OpenID Connect Core 1.0`_.
+
+- Published meta-data document at ``<issuer>/.well-known/openid-configuration`` as specified in `OpenID Connect Discovery 1.0`_.
+
+- Support for Authorization code flow (``response_type=code``) with ``response_mode=query``.
+
+- Support for client authentication using client ID and client secret and without public key cryptography.
