JoinJail
by Codx
Server owners who run offline-mode servers can use JoinJail to hold newly joining players in a bedrock jail until they set a password.
What it does
JoinJail generates a small bedrock jail far from the world spawn. Newly joining players appear inside it, and the only way out is to set a password with the command provided. Until then the player stays locked in, which lets a server check that the account behind an offline-mode login belongs to the person using it.
The mod also manages access in a few other ways. A selected player can be banned with a given reason, a ban can be reversed with the regular pardon command, and a list command shows every whitelisted player. A player who dies in the jail respawns inside it on the first tick after spawning. Fabric API is required.
JoinJail is server-side only, so players join without installing anything. It is published for Fabric alone, for 1.19.3, 1.19.4 and 1.20, with 1.5.0 for 1.20 as the latest file, released under the MIT License. The code is not open source.
