Auto Reauth
by connorslade
Auto Reauth renews a Minecraft login session on its own once the Microsoft token expires, so the game does not need a restart to sign in again.
What it does
Without the mod, a session typically expires after about a day, and the player has to restart the game to sign in again. Auto Reauth stores authentication tokens after the first sign-in through its own login flow, then re-authenticates the session when it expires. The player can also trigger a re-authentication by hand from the config screen.
The config screen is reached from Mod Menu, which is optional. Each time the multiplayer menu opens, Auto Reauth checks the session status and re-authenticates only when it is needed. If a refresh fails, the mod tries signing in again. Tokens are reported to expire after some time, around 90 days, and that is when problems can start appearing without the mod.
The mod requires Fabric API and runs client-side only, so servers do not need it and players join without installing anything. It is open source under the MIT License, with public links for source code and an issue tracker. Files target Fabric for game versions 1.20.1 – 26.2, with 0.4.1 as the latest file for 26.2, published 2026-06-25.
Key features
Automatic session renewal
The mod re-authenticates the session when it expires, so a restart is not needed to keep playing.
Manual re-authentication
A player can start a new sign-in by hand from the config screen at any time.
Token storage
Authentication tokens are stored after the first Microsoft login, so later renewals reuse them.
Status check on multiplayer
Opening the multiplayer menu triggers a check of the session status, with a new login only when needed.

Auto Login is client-side only on Fabric for 1.21.11 – 26.3 under the MIT License, a narrower version range than Auto Reauth.
