Actively maintained fork of FastLogin — auto-detect and login premium Minecraft accounts on offline-mode servers.

For base features, platform support, and technical details, see FastLogin's README.

• AuthMe 6.0 compatibility — auto-detects AuthMe version, adapts premium flow and command namespace (/flp) without user config.
• Offline Whitelist — block unknown cracked players, allow premium via Mojang API. Replaces the upstream switchMode which had issues with new premium players being kicked.
• Multi-language — built-in English and Chinese, custom language files supported, bilingual config comments.
• SQLite concurrency — WAL mode, busy timeout, thread-safe operations with ReentrantLock.
• Session retry — Mojang session verification retries on network errors instead of failing immediately.
• SkinsRestorer compatibility — no longer overrides skins set via SkinsRestorer.
• fldelete rewrite — localized messages, premium player protection, BungeeCord support.
• Log readability — human-readable login flow messages instead of raw packet dumps.

Spigot / Paper: install ProtocolLib → drop FastLoginPlusBukkit.jar in plugins/ → set online-mode=false

BungeeCord / Velocity: install on both proxy and backend → configure allowed-proxies.txt → enable IP forwarding → set online-mode=false on both → full guide

For detailed installation steps, see FastLogin's install guide.

Add .other suffix for targeting other players (default: op).

Note: When AuthMe 6.0+ is detected, /premium and /cracked are registered under /flp (e.g. /flp premium) to avoid command conflict. /fldelete is unchanged.

Exports %fastloginplus_status% — values: Premium, Cracked, Unknown.
