SpawnAuth integrates with AuthMe or nLogin to isolate unauthenticated players in a void limbo world. It saves their original location and restores it after login, while a protected auth spawn keeps your main world safe.

It fixes common issues found when using AuthMe or nLogin alone. Their built-in spawn/limbo handling can be disabled, as it often causes problems like players getting stuck at spawn, leaving after death instead of respawning, and other edge-case bugs.
