# Setting up matrix-registration (optional)
|
||||
|
||||
The playbook can install and configure [matrix-registration](https://github.com/ZerataX/matrix-registration) for you.
|
||||
|
||||
> 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.DOMAIN/matrix-registration`
|
||||
|
||||
|
||||
## Installing
|
||||
|
||||
Adjust your playbook configuration (your `inventory/host_vars/matrix.DOMAIN/vars.yml` file):
|
||||
|
||||
```yaml
|
||||
matrix_registration_enabled: true
|
||||
|
||||
# Generate a strong secret using: `pwgen -s 64 1`.
|
||||
matrix_registration_admin_secret: "ENTER_SOME_SECRET_HERE"
|
||||
```
|
||||
|
||||
Then, run the [installation](installing.md) command again:
|
||||
|
||||
```
|
||||
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
|
||||
```
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
**matrix-registration** gets exposed at `https:///matrix.DOMAIN/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 API (the one for creating unique registration tokens) easy to use via the playbook.
|
||||
|
||||
**To create a new user registration token (link)**, use this command:
|
||||
|
||||
```
|
||||
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.
