Getting Started with Auth Back

Setting Up Your Public Key

Auth Back Mod lets you play on multiplayer servers even when Minecraft's login system is down. To use it, both your game and the server must have the mod installed.

Open Options, select Online…, then AuthBack… to access the main menu. In the Key management section, find and copy your personal public key. This key proves your identity to the server safely.

If you can't join during a login outage, share your public key with the server owner. They can add you by typing a command in their console using your player name and public key. Once added, you'll automatically connect using your saved login details. The mod remembers data from your last visit (up to 36 days) and speeds up connections by reducing requests to main servers.
