The mod is an unmaintainable mess due to having to support 1.8 - 1.19 and 2 different mod loaders (3 if NeoForge would be added). Updating the mod itself wouldn't be too difficult, but fixing the gradle buildfiles and attempting add more versions (1.20) would just make the whole setup even more unstable (and time consuming to fix again).

Open source minecraft authentication protocol for proxies

This mod provides an easy and secure interface for proxies to authenticate to an online mode server. This works by forwarding the authentication request to the client and letting it do the authentication.

When using this mod, your session or private keys WILL NOT be sent to the server at any point. Everything is done clientside and with your confirmation.

• Fabric 1.14 - 1.19.3
• Forge 1.14 - 1.19.3
• Forge 1.8 - 1.12.2

• ViaProxy: ViaProxy lets players join on every classic, alpha, beta and release server. To try it out join viaproxy.raphimc.net with a minecraft 1.8 - latest client. OpenAuthMod allows you to join online mode servers over that proxy.
• VIAaaS: VIAaaS is a standalone ViaVersion proxy.

To run this mod in a development environment you simply need to import the project as a gradle project into your IDE.
To build it using the command line execute gradlew build
