I have seen people wanting to login in to there Dev client, the old way of adding the arg --username and --password does not work with the new Microsoft Minecraft accounts. Well that's not a problem we can add ReAuth to Mcreator, load the game, go to Multiplayer and click ReAuth Login button
at the top left of the page and login.
Sorry this is forge only they haven't updated the Fabric versions in a long time.
Supports:
Forge 1.14.4 - 4.0.7
Forge 1.15.2 - 4.0.7
Forge 1.16.5 - 4.0.7
Forge 1.18.2 - 4.0.7
Forge 1.19.2 - 4.0.7
Change Log:
1.0.0.2 - Updated to 4.0.7, to this date we still don't have 1.19.4 + support but it does work with 1.14.4 up to 1.19.2
Note:
In 1.18.2/1.19.2 login might not always work if you use This Device, if this happens use the Any Device option it will send you to the login screen you use for Pocket/Switch
and you can login that way, make sure you use Save profile to Config if you don't want to keep going to the URL each time you launch, if you click that you can click Login as USERNAME to log back in.
This DOES log you in to the single player and it dose work with your own skin.

All Copyright belongs to the ReAuth creator I make it so we can use it in MCreator.
