The plugin ensures that authentication is unobtrusive once complete. Passwords are securely hashed using bcrypt, and all database operations run asynchronously to avoid impacting gameplay. With built-in Floodgate support, Bedrock players can join automatically without manually entering login commands, while Java players can authenticate as usual.

Standalone & Velocity Compatible

With built-in Floodgate support, Bedrock players can join automatically without manually entering login commands, while Java players can authenticate as usual.
Works as a standalone plugin or alongside NxAuthVelocity for Velocity proxies. Premium players can auto-login while offline/cracked players use the familiar /login command. This ensures seamless support across different server setups.
Floodgate & Bedrock Ready
Bedrock players authenticated via Floodgate are automatically logged in, eliminating unnecessary /login or /register steps and creating a smoother experience across platforms.
Custom Auth & Spawn Locations
Admins can define separate spawn points for authentication and main gameplay. Players are spawned to the auth spawn when logging in, protecting against coordinate leaks and keeping the authentication process isolated from the main world.
Automated Backups
NxAuth integrates with our backup panel to allow automatic hourly backups of your database and config files. Just copy the command from the panel and execute it in-game as an operator — backups then run automatically without any additional setup.
