I've already bought minecraft but I've lost the account I bought it with is there any way...

Hi there! Yes, there should be a sign-in for other Microsoft accounts in the Launcher. If you are already signed in to other accounts, you can click on the drop down at the upper left of the launcher then add an account.

Thank you, still I remember there was a way just to switch accounts in the launcher if you signed out and signed in with a different account, is this no longer a feature?

Hello and welcome to our community!

We’re excited to have you here and have great conversations! I'd be happy to be of assistance.

I'm sorry to hear you're experiencing this issue. I understand this may be unexpected. Please note that the game is tied to the Microsoft account that was used to purchase it. Currently, there's no way to transfer game entitlements or licenses from one account to another.

To play the game on your PC, you'll need to sign in with the account that originally purchased the game on both the Microsoft Store app and the Xbox app (or the Minecraft Launcher, if applicable). This ensures that the system can detect the game entitlement linked to your account, allowing you to play the game without any issues.

Do you still have access to your Old account where the game was purchased to? If you no longer have access to that account, I suggest recovering it. You can submit a request for account recovery at this link: https://account.live.com/acsr. Once you fill out the form, someone from the Microsoft account recovery team will reach out through your email to help you recover your account. Additionally, please avoid leaving any fields blank when filling out the form. If you're unsure about certain information, make your best guess instead.

Hope this helps. Please let me know if you need further assistance.

Thanks for the info, but there's surely a way for Microsoft to verify that I already own the game? They clearly display the packages that I've bought for Minecraft, Is there a way trace the keys?
