Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password`

We are going to use **FastAPI** security utilities to get the `username` and `password`.

OAuth2 specifies that when using the "password flow" (that we are using) the client/user must send a `username` and `password` fields as form data.

repositories {
    maven {
        url "sftp://repo.mycompany.com:22/maven2"
        credentials {
            username "user"
            password "password"
        }
    }

    ivy {
        url "sftp://repo.mycompany.com:22/repo"
        credentials {
            username "user"
            password "password"
        }
    }
}
// end::maven-ivy-repository-auth[]

    github enables querying for PR and also create issue using rest endpoint
    username has the login username of the Pull Request Event
  @return {string} Return the domain name of the user's email. Empty string if not found
*/

const get_email_domain = async ({github, username}) => {
  const user = await github.rest.users.getByUsername({
    username
  });
  if (user.status >= 400) {
    console.log(user);
