Minecraft Technic launcher login with microsoft?

My colleague recently bought minecraft java edition and we shared a server for hexxit so we can play together but he can't log into the technic launcher with the email and password from minecraft can someone help?

Does any error or message come when he enters it?

There's currently nothing you can do about that. The technology launcher just doesn't have a Microsoft login yet.

Use Vanilla Launcher, install the right Forge and add all mods yourself, then it works for him too.
