AlwaysAuth
AlwaysAuth is a fallback authentication solution for Minecraft servers that ensures your players can log in even if Mojang's authentication servers experience downtime. Unlike traditional offline-mode workarounds, AlwaysAuth keeps your server in online mode while providing a seamless failover mechanism to a local authentication system.
How It Works
AlwaysAuth operates by inserting a local authentication server between your Minecraft server and Mojang’s official authentication servers:
- When a player tries to log in, AlwaysAuth first sends the authentication request to Mojang.
- If Mojang is online and responds, the request passes back to your server normally.
- If Mojang is offline, AlwaysAuth uses its local fallback system to verify the user.
This approach ensures:
- Instant failover: No waiting for periodic checks. Even short outages are handled seamlessly.
- Online mode stays enabled: You never have to switch your server to offline mode.
- Reliable authentication during extended downtime: Long outages are handled just as smoothly.
AlwaysAuth vs AlwaysOnline
| Feature | AlwaysAuth | AlwaysOnline |
|---|---|---|
| Spigot Support | ✅ | ✅ |
| Paper Support | ✅ | ✅ |
| BungeeCord Support | ❌* | ✅ |
| Velocity Support | ✅ | ✅ |
| Sponge Support | ❌** | ✅ |
| Fabric Support | ✅ | ❌ |
| NeoForge Support | ✅ | ❌ |
| Instant Failover | ✅ | ❌ |
| Online Mode Stays Enabled | ✅ | ❌ |
| Remote Database Support | ✅ | ✅ |
| Records Metrics | ❌ | ✅ |
| Multiple Security Modes | ✅ | ❌ |
| IP-Based Validation | ✅ | ✅ |
*There is no possible way to set a custom session server on bungeecord, nor ever will according to md_5, see here. I will be creating a work around that involves many extra steps, however I recommend switching to Velocity or using the Standalone jar
**Sponge support is planned to be added later, I am just unfamiliar with the SpongeAPI
Key Benefits
- Keep Online Mode Active: No need to compromise security for downtime.
- Supports Multiple Platforms: Works with Spigot, Paper, BungeeCord, Velocity, Fabric, and NeoForge.
- Flexible Authentication: Choose from multiple security modes and fallback methods.
- Reliable: Handles both short blips and extended Mojang outages effortlessly.
Installation
- Download the AlwaysAuth plugin for your server platform.
- Place the plugin in your server’s
plugins(or equivalent) folder. - Restart your server.
- Configure AlwaysAuth in the config file to enable features like local authentication, remote database support, or IP-based validation.
Give yourself the permission alwaysauth.admin to access the commands
Configuration
AlwaysAuth provides a flexible configuration file where you can:
- Enable or disable specific fallback methods.
- Set up remote databases for cross-server authentication.
- Choose between different security modes.
