I'm using Firebase Auth for a site and chosen password authentication and Google Sign In. When I ran it I got the following:
{"error":{"code":403,"message":"Requests to this API identitytoolkit method google.cloud.identitytoolkit.v1.AuthenticationService.SignUp are blocked.","errors":[{"message":"Requests to this API identitytoolkit method google.cloud.identitytoolkit.v1.AuthenticationService.SignUp are blocked.","domain":"global","reason":"forbidden"}],"status":"PERMISSION_DENIED"}}
I already enabled both password and Google Sign In from Firebase console and also enabled the Identity Toolkit API in my Google Cloud Platform console but I still get this error.
