Fivem Steam Authenticator

This script enforces Steam-only connections on FiveM servers by hooking into the playerConnecting event and rejecting any player without a valid steam: identifier. It provides clean deferral messages and handles edge cases like missing source values without adding overhead.

Designed for roleplay and community servers, the resource works with any FiveM setup and requires only a Steam Web API key in server.cfg for reliable authentication checks.
