FriendSMPGuard
About
A mandatory client mod for FriendSMP that enforces mod presence, version checking, and one-time access code validation. Players must have the mod installed to join, with a valid code (FSG-XXXX-XXXX-XXXX format) that binds to UUID/nickname and expires after 5 weeks. Includes client-side code entry screen, server-side admin commands, login logging, and pending-player timeout detection.
