It can be used for an invitation-based server, +where you invite someone by sending them a registration token. They can register as normal but have to provide a valid +registration token in a final step of the registration. + +See the project's [documentation](https://github.com/moan0s/matrix-registration-bot#supported-commands) to learn what it +does and why it might be useful to you. + + +## Registering the bot user + +By default, the playbook will set use the bot with a username like this: `@bot.matrix-registration-bot:DOMAIN`. + +(to use a different username, adjust the `matrix_bot_matrix_registration_bot_matrix_user_id_localpart` variable). + +You **need to register the bot user manually** before setting up the bot. You can use the playbook to [register a new user](registering-users.md): + +``` +ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=bot.matrix-registration-bot password=PASSWORD_FOR_THE_BOT admin=yes' --tags=register-user +``` + +Choose a strong password for the bot. You can generate a good password with a command like this: `pwgen -s 64 1`. + +## Obtaining an admin access token + +In order to use the bot you need to add an admin user's access token token to the configuration. As you created an admin user for the +bot, it is recommended to obtain an access token by logging into Element/Schildichat with the bot account +(using the password you set) and navigate to `Settings->Help&About` and scroll to the bottom. +You can expand "Access token" to copy it. + +![Obatining an admin access token with Element](assets/obtain_admin_access_token_element.png) + +**IMPORTANT**: once you copy the token, just close the Matrix client window/tab. Do not "log out", as that would invalidate the token. + +## Adjusting the playbook configuration + +Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file: + +```yaml +matrix_bot_matrix_registration_bot_enabled: true +# Token obtained via logging into the bot account (see above) +matrix_bot_matrix_registration_bot_bot_access_token: "syt_bW9hbm9z_XXXXXXXXXXXXXr_2kuzbE" + +# Enables registration +matrix_synapse_enable_registration: true + +# Restrict registration to users with a token +matrix_synapse_registration_requires_token: true +``` + + +## Installing + +After configuring the playbook, run the [installation](installing.md) command again: + +``` +ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start +``` + + +## Usage + +To use the bot, create a **non-encrypted** room and invite `@bot.matrix-reminder-bot:DOMAIN` (where `YOUR_DOMAIN` is your base domain, not the `matrix.` domain). + +In this room send `help` and the bot will reply with all options. + +You can also refer to the upstream [Usage documentation](https://github.com/moan0s/matrix-registration-bot#supported-commands). +If you have any questions, or if you need help setting it up, read the [troublshooting guide](https://github.com/moan0s/matrix-registration-bot/blob/main/docs/troubleshooting.md) +or join [#matrix-registration-bot:hyteck.de](https://matrix.to/#/#matrix-registration-bot:hyteck.de). diff --git a/docs/configuring-playbook.md b/docs/configuring-playbook.md index c842a870..5233a662 100644 --- a/docs/configuring-playbook.md +++ b/docs/configuring-playbook.md @@ -151,6 +151,7 @@ When you're done with all the configuration you'd like to do, continue with [Ins -
