Setting up Mautrix Google Chat (optional)

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

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

To enable the Google Chat bridge just use the following playbook configuration:

matrix_mautrix_googlechat_enabled: true

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 (see Usage).

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-googlechat", "initial_device_display_name": "Mautrix-googlechat"}' \
https://matrix.DOMAIN/_matrix/client/r0/login

• send the access token to the bot. Example: login-matrix MATRIX_ACCESS_TOKEN_HERE

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

Usage

Once the bot is enabled you need to start a chat with googlechat bridge bot with handle @googlechatbot:YOUR_DOMAIN (where YOUR_DOMAIN is your base domain, not the matrix. domain).

Send login to the bridge bot to receive a link to the portal from which you can enable the bridging. Open the link sent by the bot and follow the instructions.

Automatic login may not work. If it does not, reload the page and select the "Manual login" checkbox before starting. Manual login involves logging into your Google account normally and then manually getting the OAuth token from browser cookies with developer tools.

Once logged in, recent chats should show up as new conversations automatically. Other chats will get portals as you receive messages.

You can learn more about authentication from the bridge's official documentation on Authentication.

After successfully enabling bridging, you may wish to set up Double Puppeting, if you haven't already done so.
