AuthLoger
by HangerPlayz
AuthLoger is a Fabric logging mod that records player authentication events on a server, so administrators can see logins as they happen.
What it does
Once installed on a server, AuthLoger writes authentication events to the server log. Administrators can follow join activity and other authentication-related actions in one place, which helps with moderation and day-to-day server management.
The mod is described as lightweight and optimized, with minimal performance impact. It runs on Fabric only, for 1.20.4 – 26.1.2, and is client-side only, so players need nothing installed and only the server side is involved. It is released under the MIT License and is not open source.
Key features
Login activity logging
Player authentication events are written to the server log, showing when accounts join and what happens during login.
Login activity in server logs
Login activity appears directly in the server logs, where it can be read alongside other server output.
Authentication action records
Authentication actions are recorded for each server and password setup, which keeps each record tied to the server it came from.
Admin activity lookup
Logged join and authentication actions give administrators a record to check when reviewing a player's activity.
