初步想法是将此mod迁移至1.17+版本，但我现在没时间（逃）

Fabric mod for Minecraft: Java Edition to protect offline mode servers adding /login and /register. This is a server-side mod, clients don't have to download it.

• Players are invulnerable until they log in
• Players can't interact with the world until they log in
• Players can't move until they log in
• Players can't chat or use commands (only /login and /register) until they log in
• Passwords are saved in ./registered-players.json
• Maybe I'll add more

• /register <newPassword> <confirmPassword>
• /login <password>
