Setting up Mautrix Telegram (optional)

The playbook can install and configure mautrix-telegram for you.

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

You'll need to obtain API keys from https://my.telegram.org/apps and then use the following playbook configuration:

matrix_mautrix_telegram_enabled: true
matrix_mautrix_telegram_api_id: YOUR_TELEGRAM_APP_ID
matrix_mautrix_telegram_api_hash: YOUR_TELEGRAM_API_HASH

Note: For architectures different from amd64 you need to trigger a local rebuild:

matrix_mautrix_telegram_container_self_build: true

Lastly, to take these changes into effect, re-run the playbook:

ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start

Set up Double Puppeting

If you'd like to use Double Puppeting (hint: you most likely do), you have 2 ways of going about it.

Method 1: automatically, by enabling Shared Secret Auth

The bridge will automatically perform Double Puppeting if you enable Shared Secret Auth for this playbook.

This is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.

Method 2: manually, by asking each user to provide a working access token

Note: This method for enabling Double Puppeting can be configured only after you've already set up bridging.

When using this method, each user that wishes to enable Double Puppeting needs to follow the following steps:

• retrieve a Matrix access token for yourself. You can use the following command:

curl \
--data '{"identifier": {"type": "m.id.user", "user": "YOUR_MATRIX_USERNAME" }, "password": "YOUR_MATRIX_PASSWORD", "type": "m.login.password", "device_id": "Mautrix-Telegram", "initial_device_display_name": "Mautrix-Telegram"}' \
https://matrix.DOMAIN/_matrix/client/r0/login

• send login-matrix to the bot and follow instructions about how to send the access token to it

• make sure you don't log out the Mautrix-Telegram device some time in the future, as that would break the Double Puppeting feature

Usage

You then need to start a chat with @telegrambot:YOUR_DOMAIN (where YOUR_DOMAIN is your base domain, not the matrix. domain).

If you want to use the relay-bot feature (relay bot documentation), which allows anonymous user to chat with telegram users, use the following additional playbook configuration:

matrix_mautrix_telegram_bot_token: YOUR_TELEGRAM_BOT_TOKEN
