Github Warning: Github Password in 07. Launching a Multibranch Jenkins Pipeline

I got an email from Github related to the exercise 07. Pipeline as a Code with Jenkinsfile: Launching a Multibranch Jenkins Pipeline

Brownouts and and Removal indicated:

... you used a password to access an endpoint through the GitHub API using ObsoleteUrlFactory:
https://api.github.com/user
Basic authentication using a password to the API is deprecated and will soon no longer work. Visit https://developer.github.com/changes/2020-02-14-deprecating-password-auth/ for more information around suggested workarounds and removal dates.

Remediation:

"GitHub no longer supports basic authentication using a username and password. Instead, we recommend using personal access tokens or the web application flow."
