Register Minecraft?

I wanted to ask since Mojang was bought by Microsoft whether you have to register via Microsoft. If so, how do I manage to change my Mojang account to Microsoft because mri says I have to buy it again.

Is there no customer service from Minecraft or Mojang or Mircosoft?

I don't think I'll buy again.

At the moment you still need a Mojang account. The account change will take place in the next few days.

Ahh ok thanks I'm just very inactive in Minecraft I've just noticed it by the way. But I definitely won't buy it again, so I'd better ask again

Just have a look at the launcher every now and then in the next few days, everything should be announced there.
