OfflinePass
by Stabosa97
OfflinePass lets a server with offline-mode players check each joining username against a password list, so the server accepts only the people who hold the right password.
What it does
Offline servers normally cannot use a whitelist, because the server has no way to confirm who is connecting. OfflinePass covers that gap: the server owner stores a password for each allowed username in a configuration file, and a player who joins must send the matching password first. A name change alone does not get a player in, since the password is tied to the username that is requested.
The password file is world/serverconfig/serverofflinewhitelist.toml, and the entries follow a simple username:password format. Passwords can be written by hand or generated by the mod, which uses special characters or only numbers depending on the option chosen. Generated passwords can then be sent to friends, and the server owner can also receive one. The login process is handled by the client, which sends the password packet, and the server checks it against the list before letting the player in.
OfflinePass is a server-side check and needs both the server and every player to have it installed. It is published for Forge only, with a single game version, 1.20.1, and its latest file is 1.0.0. The mod is released under All rights reserved, so it is not open source.
Key features
Password-gated joining
Only players whose username and password match an entry in the file are let in, even on offline-mode servers.
Generated passwords
The mod can generate passwords using special characters or numbers only, so owners do not have to invent them.
Plain-text password file
Passwords are stored in world/serverconfig/serverofflinewhitelist.toml, one username and password per entry.
No login commands
Players do not type a login command after joining, so the check happens once at connection and needs no in-game step.

userpasswords = ["1234:stabbyeli", "insertpasswordhere:codinghuman", "passworddd:RDJX3", "password:username"] Q: Why would I wanna add this to my offline server? A: Well, first of all, whitelist doesn’t work for offline servers! And if it did, it wouldn’t even matter – you can change your name to ANYTHING on offline…
