Hi there,
Over the course of 2021, millions of Java Edition players switched over to Microsoft accounts. We’re happy that so many of you are already enjoying benefits like a single account for all Minecraft games, two-factor authentication and improved player safety.
Starting on 10 March 2022, your Mojang account, which is used to play Minecraft: Java Edition, must be migrated to a Microsoft account to continue playing. Don't worry – everything about your game and how you play will remain the same, including your in-game username, progress, creations and skins. The only change is how you'll log in. Plus, we'll give you a special cape just for migrating!

MIGRATE NOW: https://minecraft.net/move

KEEP YOUR ACCOUNT SAFE

Be sure to protect your account during migration. Never enter your account details on third-party websites. If you receive an email that asks for your account information, do not respond. Moving your account can only be done through the launcher or on your Minecraft.net account page and only takes a couple of minutes. Mojang will never ask for your account information in any other way. Beware of phishing attempts and keep your account safe!

I closed my (basically unused after one day) #Minecraft account a long time ago. I'm not going to create a #Microsoft account in order to play a game that I don't play.
