FastLoginPlus

recommend reading Full Documentation before use→

An actively maintained fork of FastLogin with continuous updates and new features. MIT licensed; original copyright preserved.

FastLoginPlus automatically logs in premium Minecraft players on offline servers. When a player joins, their name is checked against the Mojang API — if they own the game, they skip the auth plugin entirely and get their real UUID and skin. No client mods, no password prompts for legitimate players.

What it does

• Auto-register premium players on first join
• Premium auto-login via Mojang API
• Premium UUID and Premium Skin forwarding
• Standalone, or behind a BungeeCord/Velocity proxy

Why this fork(What's new)

• AuthMeReloaded 6.0 support — zero manual config
• SkinsRestorer compatibility
• Folia support
• Multi-layer anti-bot: per-IP rate limiting, burst detection, temporary IP bans, trusted IP whitelist
• SQLite on proxies (upstream only supported MySQL/MariaDB)
• Offline whitelist — premium players join freely, unknown cracked players are blocked
• Multi-language: English & 中文 built in
• session retry on network errors

Requirements

• An offline server
• An auth plugin (AuthMe, LoginSecurity, CrazyLogin, etc.)
