Strong authentication credentials are essential for safeguarding GitHub accounts, with a focus on using strong, unique passwords and enabling two-factor authentication (2FA). GitHub is enhancing security by implementing features that encourage users to select non-compromised passwords, utilizing data from the HaveIBeenPwned.com project to identify compromised credentials. Users employing compromised passwords will be prompted to change them during login or registration processes. Additionally, GitHub will periodically remind users with 2FA enabled to review their setup and recovery options to prevent account lockout due to lost credentials. The platform advises the use of cloud-synchronized password managers and authenticator applications to ensure password and 2FA recovery options are securely backed up. GitHub also recommends storing backup codes securely and reviewing other credentials like SSH keys and OAuth authorizations regularly. These measures aim to balance security, usability, and recoverability, and users are encouraged to periodically review and update their account security settings.
