This is a heads-up to everyone who might not have migrated their Mojang Accounts to Microsoft ones yet: you have until 19 September at 11am (Eastern time), after which you will no longer be able to login.

This has been announced back in 2020 and most everyone here has already done it. Still, you might want to double-check just to make sure: if you don't do it, you will not be able to play anymore!
