Beginning November 13th, 2020, GitHub will require token-based authentication, such as personal access tokens, OAuth tokens, or GitHub App installation tokens, for all authenticated API operations on GitHub.com, moving away from password-based authentication to enhance security. This change aims to provide benefits such as unique, revocable, limited, and random tokens, reducing vulnerabilities associated with reused passwords. Although GitHub Enterprise Server users are unaffected, those using Git operations will eventually need to adopt token or SSH key authentication. The transition encourages developers and integrators to update their authentication methods to avoid disruption, with further requirements for Git operations expected by mid-2021. Two-factor authentication users will not be affected by future Git changes, and GitHub Apps remain unaffected as they do not use password authentication. GitHub emphasizes the importance of these changes for improved security and urges users to prepare by updating their systems accordingly.
