REND comes with its own user session manager, but it can also be configured to use uSessions.

It also supports multiple profiles (different sessions for different user profiles).

It will create a session for each newly created user profile.

For each session there is a corresponding file (by default there is a .u0 file which contains the information about the user, like its name, its username and password, etc.), and the .u0 file is automatically created when it is mounted (with mount -r in the mount path).
