Limbo Auth

Limbo Auth is the best (and only) Authorization plugin for Limbo (https://github.com/LOOHP/Limbo/).

Why use Limbo Auth

Secure

Limbo Auth is built with security in mind, everything is encrypted BEFORE it gets sent to the database, so even with a MySQL database breach, none of your users login passwords wil be compromised!

Lightweight and Fast

Limbo Auth is lightweight and fast! Encryption and Dencryption of the passwords happens in milliseconds, as does API triggers!

Customizable

Almost every aspect of Limbo Auth is customizable, down to the messages sent to the players, to the commands ran on correct authorization! And if the config isnt enough to satisfy your needs, there is a simple yet robust API that you can use to create your own plugin addons!

Setup

1. Stop Limbo server
2. Install latest version of Limbo Auth into plugins folder
3. OPTIONAL Configure MySQL (SQLite will be used if not!) in config.yml
4. OPTIONAL Configure any messages you'd like too in messages.yml
5. OPTIONAL Configure the commands that are run when a player is authorized in config.yml
6. Start the server and enjoy Limbo Auth!
