Custom Login

Allows you to log in to servers which use a compatible Yggdrasil authserver. You probably don't need this mod unless a server admin/operator told you to install it. Due to the way this works, you will have to add the server in your server list (not using Direct Connect), and you will have to wait for the MOTD to load before clicking Play.

For server admins

If your server connects to an Yggdrasil instance which is not the normal Mojang one, such as yggdrasil-server (disclaimer: I wrote it), you can add an invisible sequence to the end of your MOTD to advertise that instance to clients using this mod, giving players an in-game login interface rather than having to use a custom launcher or setting JVM arguments.
