During two-factor authentication and when entering sudo mode for sensitive actions on GitHub.com, TOTP codes could be successfully used multiple times within their validity window. To improve security, this reuse is no longer allowed on GitHub.com, and will be updated in GHES with version 3.10.

Systems that have attempted to script the login flow, across multiple parallel jobs, may break as a result of this change.

Learn more about two-factor authentication with TOTP.
