Federation allows for an unlimited number of workspaces to communicate with each other. Federating a workspace makes it visible to other workspaces over the federated network, thus making communication with other federation-enabled servers possible. It offers a great way to collaborate with partners, customers, and other organizations, regardless of which chat platform they use.
To access Federation on your workspace,
Navigate to Administration > Workspace > Settings > Federation.
Rocket.Chat basic federation is deprecated from version 6.0. Thus, we strongly recommend using Matrix Bridge.
