BetterAuth

by Scrimchic

BetterAuth is a client-side Fabric utility that masks passwords and automates logins on saved servers, keeping authentication commands out of view.

FabricClient-side onlyMIT LicenseOpen source1.16.2 – 1.21.8

What it does

BetterAuth hides sensitive authentication commands from the chat box and from the vanilla command suggestion popup, so a password typed for a server login is not displayed. Players can manage a list of saved servers, view or delete stored entries, and set up custom commands that mask specific servers. Auto-login and auto-saving can be toggled on or off as needed.

The mod targets players who log into servers that use password commands. Installation requires Fabric API alongside the mod. Only the client needs BetterAuth, so server owners do not have to add anything. Files exist for Fabric across 18 release versions, 1.16.2 – 1.21.8, and the latest file is for 1.21.8. The code is released under the MIT License and is open source, with public source code and an issue tracker.

Key features

  1. Masked authentication commands

    Login and registration commands are hidden in the chat and kept out of the vanilla command suggestion popup.

  2. Auto-login for saved servers

    Saved servers can log the player in automatically, and the behavior can be turned off per toggle.

  3. Saved server manager

    A view lists saved servers, reveals stored passwords on request and lets the player delete individual entries.

  4. Custom masking rules

    Custom commands can be marked so that masking applies only to specific servers.

  5. Translated interface

    The interface is available in English, Ukrainian, Russian and Kazakh.

How it compares

Full comparison

PasswordManager for AuthMe is also client-side and open source under the MIT License, but it covers 1.18.2 – 1.21.4 and is Fabric only. Autologin is client-side, covers only 1.21.11 and is not open source. Lyumix Discord Auth is server-side only and open source under the MIT License, so it runs on the server rather than in the player's client.
