Unity Authentication - How to check token validity?
After the user sign in and make requests to my backend (not Unity project), I need a way to verify that the user sending the request is valid.
Is there an API that can check the validity of the access token returned after user sign in through Unity AuthenticationService?

It seems like Unity does not provide any API for that. I done it by validating the signature of the JWT using the Unity jwks.
