I want to play Minecraft realms but i need to migrate my account. However, to migrate my account I need to know my email which i forgot

Tte

It is very interesting

You deserved it

Unfortunately if you forgot which email you used to create your account (especially if you used a temporary or fake one) you are out of luck and will have to re-buy the game.

I would log into every email account you can remember having and checking to see if they have the Minecraft confirmation email. (You did save your receipt right?) If you get lucky, you might find it and then know what email it is.
