Modern graphical authentication for Paper servers.
No chat commands. No bloat. Just a clean dialog UI that gets players in fast and safe.


✨ Features

  • Dialog UI — graphical login & register screens, no typing commands in chat
  • Smart version routing — pre-join dialog on 1.21.11+, post-join dialog on 1.21.4–1.21.10
  • Full lockdown — movement, chat, commands, inventory all blocked until authenticated
  • Session auto-login — returning players skip the dialog if their session is still valid
  • BCrypt security — configurable cost factor, brute-force delay, max attempt kicks
  • AuthMe migration — one command imports all accounts, supports SHA256 & BCrypt hashes
  • Custom branding — change the dialog title prefix to match your server
  • Async everything — HikariCP + SQLite with WAL mode, zero server lag
