# Setting up the REST authentication password provider module (optional, advanced)

The playbook can install and configure [matrix-synapse-rest-auth](https://github.com/ma1uta/matrix-synapse-rest-password-provider) for you.

See that project's documentation to learn what it does and why it might be useful to you.

## Adjusting the playbook configuration

Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file (adapt to your needs):

```yaml
matrix_synapse_ext_password_provider_rest_auth_enabled: true
matrix_synapse_ext_password_provider_rest_auth_endpoint: "http://matrix-ma1sd:8090"
matrix_synapse_ext_password_provider_rest_auth_registration_enforce_lowercase: false
matrix_synapse_ext_password_provider_rest_auth_registration_profile_name_autofill: true
matrix_synapse_ext_password_provider_rest_auth_login_profile_name_autofill: false
```

## Authenticating only using a password provider

If you wish for users to **authenticate only against configured password providers** (like this one), **without consulting Synapse's local database**, feel free to disable it:

```yaml
matrix_synapse_password_config_localdb_enabled: false
```

## Installing

After configuring the playbook, run the [installation](installing.md) command: `just install-all` or `just setup-all`
