Hello Alex Castro2.



Welcome to the Microsoft Community.



Generally, when you play a Microsoft game on the Playstation, you will be prompted that you need to associate an account with it, and all you need to do is sign in to your Microsoft account (you will need to enter your account and password) in order to play the game.
Here is a page about the release of Forza Horizon 5 on PS5, there is a page about how to use your Microsoft account on Playstation, please refer to.

Thank you for your patience and understanding!

You can't do anything...once it's linked, it can't be changed:

"Linking a Microsoft account to a PSN account is on a title-by-title basis and permanent. Players have the ability to unlink the Microsoft account to that PSN account, for Forza Horizon 5, but will be constrained to relinking to only that specific and originally linked, Microsoft account."

Didn't play that game before but I do miss how in Forza Horizon 3, you could play your own music. Now with Forza Horizon 4, they removed that feature. It is ok because the game is still fun!
