Whose JWT token does Strapi return

[SorinGFS]

So the token I receive on successful authorisation is a strapi token?

Yes. You will receive the token on authentication not autorization, then you will use the token to authorize actions.

@strappinandgo

I cannot use this token directly with the provider?

Since it is a Strapi token it does not make sense to use the token directly with the provider, Strapi must validate the action using its own logic. If you want you can apply your own logic by customizing the JWT validation function.
