Migration to Microsoft accounts is mandatory and you can no longer access the Mojang accounts to play without Migrating. msft.it/6014bqZH2 ^AC

That's not what I want. I want to change the username of my old account so I can make a new one with the username of the original one. I can't migrate because I lost access to my email address god knows how long ago and now if I create a new account I need to use a different user

Please send us an email at msft.it/6011bqZKZ and we will assist. Remember to attach your Transaction ID and account name / Gamertag. ^AC

Transaction ID?

Your Transaction ID serves as your proof of purchase it's what you received when you first purchased the game. If you do not have access to that it's fine we can still help but you do need to put in a ticket for help with this. ^AC

Well would it be possible to delete the account instead? I just want that particular username freed so I can use it in my new one

Deleting accounts is something we can do but you would still need to submit a ticket for assistance. For account and player saftey reasons we can only handle account issues through the ticketing system where our account specialists can help you out. ^AC

Would I still need that ID thing if that was the case? Cause I don't have the slightest idea where it is or if I even saved it

As I said before we can help without the Transaction ID. But it is recommended if you can find it. Regardless we cannot help with this issue through social media you will need to submit a ticket for assistance with account related issues. ^AC

I greatly appreciate it. I'll get started on that tomorrow as it's stupid late where I live. Thanks!
