## Authorization Flow

- Visit <http://localhost:8080>, login will direct the user to the Google OAuth2 Auth URL to obtain a permission grant.
- The redirection URI (callback handler) receives the OAuth2 callback, verifies the state parameter, and obtains a Token.
- Using the id_token the callback handler further talks to Google OAuth2 Token URL to obtain an JWT id_token.
