how do I unlink my Microsoft account from my playstation 4 Minecraft on the computer

I am attempting to connect my microsoft account with my Ps4 account. My microsoft account is already connected to a Ps4 minecraft account. How do I find what Minecraft account is using my microsoft account and to disconnect it from it.

Even if you could disconnect it you wont be able to link a different Microsoft account.

Note: Once a Microsoft account has been linked to a PlayStation® account, neither the Microsoft account nor the PlayStation™ Network account can be associated with a different account. 

If you choose to unlink accounts, then purchases will be returned to the account which made the purchase. Even after unlinking, Microsoft and PlayStation® accounts can only be re-linked to the original account.

Note: As of March 15, 2023, please DO NOT unlink your MSA from your PlayStation account via the in-game menu. You will be unable to link it back if you do so.

This is a restriction imposed by Sony.

Hello, I hope you are well.

Please try these steps.

If the error in Minecraft on PlayStation indicates that there is a connected account and you do not remember the information, it means that the account is linked to your PlayStation Network account. To solve this, you need to unlink the Microsoft account from the game and then try to link it again.

How to unlink and relink:

1. Unlink:

Access the Minecraft settings menu on PlayStation.

Look for the option "Unlink Microsoft account" or something similar.

Follow the instructions to remove the linked account.

2. Relink:

When trying to log in to Minecraft, select the option "Sign in with Microsoft account".

Access the code redemption website on your computer or smartphone.

Enter the code that the game is displaying and log in with the Microsoft account you want to link.

If you cannot remember the email address of the Microsoft account:

Check if there is any account information saved in your browser or device.

If you can't find it, try using Microsoft's account recovery service (if the account was used for your PlayStation account, the email address must be registered

Hello ,

Thank you for posting on the Xbox forums. We understand that you are unable to unlink your Microsoft account from your PlayStation account. There is

a support article on Minecraft's support website which explains more about linking and unlinking the accounts. There is a risk involved with unlinking the accounts. The article talks more about the risks of unlinking the accounts. If you would like to continue
to learn how to unlink the account, we suggest reaching out to
Mojang support and PlayStation support. Be sure to let us know the results!

I think I'll go with the option of creating a new Microsoft account for now, and so then whenever the unlink ability on minecraft is working I'll fix my brothers account. But I thank you for your great service.

Kind regards,

Fellow Gamer
