I received this email:
On September 20th, 2020 at 10:57 (UTC) you used a password to access an endpoint through the GitHub API using curl:
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.
