RetroAuth

This modification introduces important fixes for the old Minecraft Beta 1.7.3 version, addressing authorization processes and character skin display.

Thanks to this addon, players gain the ability to connect to servers using modern authentication system, as well as see up-to-date skins that are used in newer game versions.

Important Server Note

For the authorization system to function correctly, the mod needs to be installed both on the client side and on the server side.
