-# Setting up matrix-registration (optional)
+# Setting up matrix-registration (optional, removed)
 
-> [!WARNING]
-> - This is a poorly maintained and buggy project. It's better to avoid using it.
-> - This is not related to [matrix-registration-bot](configuring-playbook-bot-matrix-registration-bot.md)
+> [!NOTE]
+> This is not related to [matrix-registration-bot](configuring-playbook-bot-matrix-registration-bot.md).
 
-The playbook can install and configure [matrix-registration](https://github.com/ZerataX/matrix-registration) for you. It is a simple python application to have a token based Matrix registration.
+🪦 The playbook used to be able to install and configure [matrix-registration](https://github.com/ZerataX/matrix-registration), but no longer includes this component, as it has been unmaintained since November, 2025.
 
-Use matrix-registration to **create unique registration links**, which people can use to register on your Matrix server. It allows certain people (these having a special link) to register a user account, **keeping your server's registration closed (private)**.
+## Uninstalling the component manually
 
-**matrix-registration** provides 2 things:
+If you still have matrix-registration installed on your Matrix server, the playbook can no longer help you uninstall it and you will need to do it manually. To uninstall manually, run these commands on the server:
 
-- **an API for creating registration tokens** (unique registration links). This API can be used via `curl` or via the playbook (see [Usage](#usage) below)
-
-- **a user registration page**, where people can use these registration tokens. By default, exposed at `https://matrix.example.com/matrix-registration`
-
-## Adjusting DNS records (optional)
-
-By default, this playbook installs the matrix-registration on the `matrix.` subdomain, at the `/matrix-registration` path (https://matrix.example.com/matrix-registration). This makes it easy to install it, because it **doesn't require additional DNS records to be set up**. If that's okay, you can skip this section.
-
-If you wish to adjust it, see the section [below](#adjusting-the-matrix-registration-url-optional) for details about DNS configuration.
-
-## Adjusting the playbook configuration
-
-To enable matrix-registration, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
-
-```yaml
-matrix_registration_enabled: true
-
-# Generate a strong secret here. You can create one with a command like `pwgen -s 64 1`.
-matrix_registration_admin_secret: "ENTER_SOME_SECRET_HERE"
-```
-
-### Adjusting the matrix-registration URL (optional)
-
-By tweaking the `matrix_registration_hostname` and `matrix_registration_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
-
-Example additional configuration for your `vars.yml` file:
-
-```yaml
-# Change the default hostname and path prefix
-matrix_registration_hostname: registration.example.com
-matrix_registration_path_prefix: /
-```
-
-If you've changed the default hostname, you may need to create a CNAME record for the matrix-registration domain (`registration.example.com`), which targets `matrix.example.com`.
-
-When setting, replace `example.com` with your own.
-
-### Extending the configuration
-
-There are some additional things you may wish to configure about the component.
-
-Take a look at:
-
-- `roles/custom/matrix-registration/defaults/main.yml` for some variables that you can customize via your `vars.yml` file
-- `roles/custom/matrix-registration/templates/config.yaml.j2` for the component's default configuration. You can override settings (even those that don't have dedicated playbook variables) using the `matrix_registration_configuration_extension_yaml` variable
-
-## Installing
-
-After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the playbook with [playbook tags](playbook-tags.md) as below:
-
-<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
 ```sh
-ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
-```
-
-The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
-
-`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
-
-## Usage
+systemctl disable --now matrix-registration.service
 
-**matrix-registration** gets exposed at `https://matrix.example.com/matrix-registration`
+rm -rf /matrix/matrix-registration
 
-It provides various [APIs](https://github.com/ZerataX/matrix-registration/wiki/api) — for creating registration tokens, listing tokens, disabling tokens, etc. To make use of all of its capabilities, consider using `curl`.
-
-We make the most common APIs easy to use via the playbook (see below).
-
-### Creating registration tokens
-
-To **create a new user registration token (link)**, use this command:
-
-```sh
-ansible-playbook -i inventory/hosts setup.yml \
---tags=generate-matrix-registration-token \
---extra-vars="one_time=yes ex_date=2021-12-31"
+/matrix/postgres/bin/cli-non-interactive -c 'DROP DATABASE matrix_registration;'
 ```
-
-The above command creates and returns a **one-time use** token, which **expires** on the 31st of December 2021. Adjust the `one_time` and `ex_date` variables as you see fit.
-
-Share the unique registration link (generated by the command above) with users to let them register on your Matrix server.
-
-### Listing registration tokens
-
-To **list the existing user registration tokens**, use this command:
-
-```sh
-ansible-playbook -i inventory/hosts setup.yml \
---tags=list-matrix-registration-tokens
-```
-
-The shortcut command with `just` program is also available: `just run-tags list-matrix-registration-tokens`
-
-## Troubleshooting
-
-As with all other services, you can find the logs in [systemd-journald](https://www.freedesktop.org/software/systemd/man/systemd-journald.service.html) by logging in to the server with SSH and running `journalctl -fu matrix-registration`.

-## Letting certain users register on your private server
-
-If you'd rather **keep your server private** (public registration closed, as is the default), and **let certain people create accounts by themselves** (instead of creating user accounts manually like this), consider installing and making use of [matrix-registration](configuring-playbook-matrix-registration.md).

 ## Enabling public user registration
 
 To **open up user registration publicly** (usually **not recommended**), add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:

+## matrix-registration has been removed from the playbook
+
+The [matrix-registration](./docs/configuring-playbook-matrix-registration.md) service has been removed from the playbook, as it has been unmaintained since November, 2025.
+
+The playbook will let you know if you're using any `matrix_registration_*` variables. You'll need to remove them from `vars.yml` and potentially [uninstall the component manually](./docs/configuring-playbook-matrix-registration.md#uninstalling-the-component-manually).
