The Forest Private Server Password & Access Rules
The easiest way to keep a private Forest world private is to be boring about access. Use a real password, rotate it when the group changes, and stop posting it in public channels where old invites never die.
Private friend group
Use one shared password and rotate it when old players leave.
Streamer/community server
Separate public info from the actual join secret and expect regular changes.
Event world
Use a temporary password and retire it after the session.
