How To Recover a Compromised Minecraft Account
CAN’T RECOVER MY MINECRAFT ACCOUNT?!
You’ll need to contact Mojang support. You may reach out to Skrill and obtain your Transaction ID, as well as evidence that you made a purchase. Then they can retrieve it for you.
To convert your Mojang account to the new version, you’ll need to login using the same username and password that you used when creating your old Minecraft accounts. After upgrading your Mojang account to a new one, you must supply an active email address where you will be sent a link to the password reset webpage.
If you have a Mojang account but can’t remember the login email, try reinstalling your password. The reset procedure will deliver an email to the address listed on your profile, notifying you which one it is. Alternatively, check other email addresses that you control.
