# Setting up matrix-registration (optional)
The playbook can install and configure [matrix-registration](https://github.com/ZerataX/matrix-registration) for you.
**WARNING**: this is a poorly maintained and buggy project. It's better to avoid using it.
**WARNING**: this is not related to [matrix-registration-bot](configuring-playbook-bot-matrix-registration-bot.md)
> matrix-registration is a simple python application to have a token based Matrix registration.
Use matrix-registration to **create unique registration links**, which people can use to register on your Matrix server. It allows you to **keep your server's registration closed (private)**, but still allow certain people (these having a special link) to register a user account.
**matrix-registration** provides 2 things:
- **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 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. Consider generating it with `pwgen -s 64 1`
matrix_registration_admin_secret: "ENTER_SOME_SECRET_HERE"
```
### Adjusting the matrix-registration URL
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.
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 `inventory/host_vars/matrix.example.com/vars.yml` file:
```yaml
# Change the default hostname and path prefix
matrix_registration_hostname: registration.example.com
matrix_registration_path_prefix: /
```
## Adjusting DNS records
If you've changed the default hostname, **you may need to adjust your DNS** records to point the matrix-registration domain to the Matrix server.
See [Configuring DNS](configuring-dns.md) for details about DNS changes.
If you've decided to use the default hostname, you won't need to do any extra DNS configuration.
## Installing
After configuring the playbook, run the [installation](installing.md) command:
```
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
```
## Usage
**matrix-registration** gets exposed at `https://matrix.example.com/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:
```bash
ansible-playbook -i inventory/hosts setup.yml \
--tags=generate-matrix-registration-token \
--extra-vars="one_time=yes ex_date=2021-12-31"
```
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:
```bash
ansible-playbook -i inventory/hosts setup.yml \
--tags=list-matrix-registration-tokens
```
