Setting up Messenger bridging via Mautrix Meta (optional)
The playbook can install and configure the mautrix-meta Messenger/Instagram bridge for you.
Since this bridge component can bridge to both Messenger and Instagram and you may wish to do both at the same time, the playbook makes it available via 2 different Ansible roles (matrix-bridge-mautrix-meta-messenger
and matrix-bridge-mautrix-meta-instagram
). The latter is a reconfigured copy of the first one (created by just rebuild-mautrix-meta-instagram
and bin/rebuild-mautrix-meta-instagram.sh
).
This documentation page only deals with the bridge's ability to bridge to Facebook Messenger. For bridging to Instagram, see Setting up Instagram bridging via Mautrix Meta.
Migrating from the old mautrix-facebook bridge
If you've been using the mautrix-facebook bridge, you may wish to get rid of it first.
To do so, send a clean-rooms
command to the management room with the old bridge bot (@facebookbot:YOUR_DOMAIN
).
This would give you a list of portals and groups of portals you may purge. Proceed with sending commands like clean recommended
, etc.
Then, consider disabling the old bridge in your configuration, so it won't recreate the portals when you receive new messages.
Configuration
Most simply, you can enable the bridge with the following playbook configuration:
matrix_mautrix_meta_messenger_enabled: true
Before proceeding to re-running the playbook, you may wish to adjust the configuration further. See below.
Bridge mode
As mentioned above, the mautrix-meta bridge supports multiple modes of operation. The bridge can pull your Messenger messages via 3 different methods:
- (
facebook
) Facebook viafacebook.com
- (
facebook-tor
) Facebook viafacebookwkhpilnemxj7asaniu7vnjjbiltxjqhye3mhbshg7kx5tfyd.onion
(Tor) - does not currently proxy media downloads - (default) (
messenger
) Messenger viamessenger.com
- usable even without a Facebook account
You may switch the mode via the matrix_mautrix_meta_messenger_meta_mode
variable. The playbook defaults to the messenger
mode, because it's most universal (every Facebook user has a Messenger account, but the opposite is not true).
Note that switching the mode (especially between facebook*
and messenger
) will intentionally make the bridge use another database (matrix_mautrix_meta_facebook
or matrix_mautrix_meta_messenger
) to isolate the 2 instances. Switching between Tor and non-Tor may be possible without dataloss, but your mileage may vary. Before switching to a new mode, you may wish to de-configure the old one (send help
to the bridge bot and unbridge your portals, etc.).
Bridge permissions
By default, any user on your homeserver will be able to use the bridge.
Different levels of permission can be granted to users:
relay
- Allowed to be relayed through the bridge, no access to commandsuser
- Use the bridge with puppetingadmin
- Use and administer the bridge
The permissions are following the sequence: nothing < relay
< user
< admin
.
The default permissions are set via matrix_mautrix_meta_messenger_bridge_permissions_default
and are somewhat like this:
matrix_mautrix_meta_messenger_bridge_permissions_default:
'*': relay
YOUR_DOMAIN: user
'{{ matrix_admin }}': admin
If you don't define the matrix_admin
in your configuration (e.g. matrix_admin: @user:YOUR_DOMAIN
), then there's no admin by default.
You may redefine matrix_mautrix_meta_messenger_bridge_permissions_default
any way you see fit, or add extra permissions using matrix_mautrix_meta_messenger_bridge_permissions_custom
like this:
matrix_mautrix_meta_messenger_bridge_permissions_custom: |
'@YOUR_USERNAME:YOUR_DOMAIN': admin
You may wish to look at roles/custom/matrix-bridge-mautrix-meta-messenger/templates/config.yaml.j2
to find more information on the permissions settings and other options you would like to configure.
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. Refer to the documentation on how to do that.
-
send the access token to the bot. Example:
login-matrix MATRIX_ACCESS_TOKEN_HERE
-
make sure you don't log out the session for which you obtained an access token some time in the future, as that would break the Double Puppeting feature
Usage
You then need to start a chat with @messengerbot:YOUR_DOMAIN
(where YOUR_DOMAIN
is your base domain, not the matrix.
domain).
You then need to send a login
command and follow the bridge bot's instructions.
Given that the bot is configured in messenger
bridge mode by default, you will need to log in to messenger.com (not facebook.com
!) and obtain the cookies from there as per the bridge's authentication instructions.
