How to distinguish if user is logged in from a Provider or from a user in Keycloak

Question

I am integrating Keycloak into a React Application. I have successfully added Google Providers in Keycloak. Now the user can either log in with Keycloak user's credentials or from Login with Google. After login how to distinguish if a user is with React or with a Provider? And how to acquire the ID of that user so for certain activities to store that ID in the database?
