{"iss":"https://securetoken.google.com/fir-jwt-token","aud":"fir-jwt-token","auth_time":1588525065,"user_id":"chOc5vIRe8SJNtdSEuTJTMT7Br23","sub":"chOc5vIRe8SJNtdSEuTJTMT7Br23","iat":1588525065,"exp":1588528665,"email":"[email protected]","email_verified":false,"firebase":{"identities":{"email":["[email protected]"]},"sign_in_provider":"password"}}
