CAN’T RECOVER MY MINECRAFT ACCOUNT?!
For legacy Minecraft accounts, you log in with your username instead of an email. If you have a legacy account and forgot your username, please contact Minecraft support. If you have a Mojang account and have forgotten the email that you log in with, try resetting your password. The reset process will send an email to the address that you have registered, letting you know which address you used. Alternatively, try other email addresses that you own. If you forget or no longer have access to an email address you might have used, please contact Minecraft support.
An older Minecraft account that has not yet been migrated uses the username to login. To reset the password for a Minecraft account (you log in with your username) you will need to visit account.mojang.com/migrate and migrate your account to a Mojang account. After doing this you will be able to reset your password.
