RaLP
by __Hantu__
Servers that need players to log in before they play can use RaLP, a Register Login Plugin that adds password-based registration and login.
What it does
RaLP requires each player to register a password and then log in before joining play. Passwords are stored with BCrypt hashing rather than as plaintext. After repeated failed attempts the mod blocks further tries for that account, which limits brute-force guessing.
The mod is published for Forge, and also runs on Paper and Spigot server platforms. Its environment is a server-side mod, so players join without installing anything. Files cover 1.17.1 – 26.2, and the latest Forge file is 0.0.1-forge for 1.20.1, released on the alpha channel. The code is open source under the GNU General Public License v3.0 only.
Key features
Password registration and login
Players register with a password on first join and must log in with it on later sessions.
BCrypt password hashing
Passwords are hashed with BCrypt, so the server does not keep them as readable text.
Anti-bruteforce blocking
Accounts are blocked after too many failed login attempts, with an optional exception list.
Multi-language messages
Built-in translations are provided for twelve languages, so messages can reach players in their own language.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Offline-mode servers
A server that does not verify accounts through Mojang can use the mod to tie each player to a password.
Who it’s for: Server owners who want to restrict access to accounts that have set a password. Players join without any client-side install.
