By default, Liveblocks is configured to work without an authentication endpoint where everyone automatically has access to rooms. This approach is great for prototyping and marketing pages where setting up your own security isn’t always required. If you want to limit access to a room for certain users, you’ll need to set up an authentication endpoint to enable permissions.
There are ways to set up authentication with Liveblocks. You can either through access token permissions where a global access token is generated with accesses are directly embedded in that token, or through fine grained ID token permissions at the room level where users get verified every time they enter the room.
