This mod adds a way to login within your game in the multiplayer screen. Simply add an account and it'll open in your default browser so you can securely login. After your first login it'll save it as a profile just like the vanilla launcher so you can instantly switch accounts.
Features:
- Supports all account login types.
- Adds a new button to the multiplayer screen to login and fix invalid sessions.
- Allows you to login to different accounts without closing your game.
- Mod only needs to be installed on the client to work.
