EasyAuth Local Sessions
by hloth
With EasyAuth Local Sessions, players who have logged in once with a password can rejoin an offline-mode server without entering it again.
What it does
After a player authenticates with a password the first time, the mod stores a generated authorization token on the player's machine. On later joins, the server can accept that token in place of the password, so the login happens without a prompt. If the server does not accept the token, the usual password flow still applies.
The mod is a Fabric patch that works through a mixin, and it needs Fabric API installed alongside it. Server owners install it on the server too, where saved tokens for joining players are kept in the EasyAuth/EasyAuthLocalSessions-server folder.
Tokens are stored locally and encrypted with a key derived from the player's UUID and IP address. The derived key is hashed again, which makes stolen token files harder to use. The author advises not installing the mod on shared or guest computers and logging out when leaving those machines. The code is open source under the MIT License. Files are published for Fabric only, for the game versions 1.20.1 – 1.20.6, and the latest file is 1.0.0 for 1.20.6, released on 2026-01-24.
Key features
Automatic re-authorization
Players who have authenticated before are logged in automatically, with no password typed on each join.
Per-server tokens
Each server gets its own stored authorization token, so a token from one server does not apply to another.
Encrypted local storage
Tokens are encrypted with a key tied to the player's UUID and IP address, and the key is hashed as well.

How it compares
RpSessionMod is client-side only and is not open source; it is published under All rights reserved for 1.20.5 – 26.2. IPAuth is server-side only, open source under the MIT License, and built for 1.17. Auto Login is client-side only, open source under the MIT License, and covers 1.21.11 – 26.3, so it does not overlap with the 1.20.1 – 1.20.6 range this mod targets.
