ReAuth Mod fixes the need to restart Minecraft when your session becomes invalid. Instead of closing the game, you can log back into your account directly from the multiplayer screen. This is a client-side mod, so it only needs to be on your game and doesn’t have to be on the server.

Features:

Adds a session indicator to the multiplayer screen, showing green for a valid session and red for an invalid one.
Lets you log in again without closing and reopening Minecraft.
Allows you to switch between different accounts while the game is still running.
Provides a quick “login and retry” button if a server connection fails due to an invalid session.
Includes an option to change your username for offline play, which can be enabled in the config.
Features a hidden button in the main menu for use with the CustomMainMenu mod.

Configuration:

You can choose to save your login information in the config file.
When saved, your details are encrypted for security.
The ability to change your username for offline mode must be enabled in the config file.
