Minecraft Mojang account migration - lost access

Hello, My name is Jesse. I'm an Independent Advisor and a member of the Microsoft community and I'd love to assist you today.

It's not in the migration instructions, but after the migration, you have to ADD a NEW account, and link it to your Microsoft account. Startup will take longer, but it sure works.

On the login prompt in the java launcher, go back. You'll see the mojang account you had been signing into - ignore it, and add a new account to the launcher. Using the email address associated with the microsoft account you just migrated to, sign in with the email address and password of your microsoft account. It's not an elegant migration on the UX side of things, but it does work.

Jesse,

Thank you so much, this has worked. You're completely right, to use the account it has to be added to the launcher, but no instructions are given to do this. Thank you so much you've been a great help

That's normal, you can't access the old Mojang account after the migration, you need to use the email you used to migrate the Mojang account to, in the launcher you need to select Minecraft Java and then Microsoft login and then use the email you use during the migration process

The Minecraft migration from Mojang is on a separate Microsoft account. How can I access my purchase?

if you cannot access your microsoft account and have 2fa active then they are right all is lost, and as the microsoft account is the account that minecraft migrated too you have now lost minecraft if you cannot access the microsoft account.
