// Deprecation Notice: GitHub will discontinue password authentication to the API.
// You must now authenticate to the GitHub API with an API token, such as an OAuth access token,
// GitHub App installation access token, or personal access token, depending on what you need to do with the token.
// Password authentication to the API will be removed on November 13, 2020.
// See the tokenauth example for details.
