Can I use 1 microsoft account for forza horizon 5 on 2 ps5's

If you are using the same PlayStation account, then the Microsoft account that is linked to it will always be linked to it. So yes, you can use it on another PS5 if you wish. Just remember, the Microsoft account will only be linked to one PlayStation account.

You can only link one account:

"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"

Hi pouyan,

Thank you for posting in Microsoft Xbox Community. I understand that you want to inquire about unlinking a Forza Horizon 5 account from your PlayStation 5.

According to Forza Horizon's FAQ, 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.

Here's the official support FAQ page for your reference:

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."

Yes. Other games are OK.

Forza horizon 4 is OK too. But I bought it.

And Forza horizon 5 uses Game Pass.

I can start Forza 5 on my PC, can not start on Xbox serious S.
