* O frontend (rodando no navegador do usuário) envia esse `username` e `password` para uma URL específica na nossa API (declarada com `tokenUrl="token"`).
* A API verifica esse `username` e `password`, e responde com um "token" (ainda não implementamos nada disso).
    * Um "token" é apenas uma string com algum conteúdo que podemos usar depois para verificar esse usuário.

## 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.
