Where can you enable two-factor authentication in GitLab?

Two-factor authentication (2FA) in GitLab enhances account security by requiring not only a password but also a second form of verification, such as a mobile app code or text message. To enable 2FA, users must navigate to their profile settings, specifically in the Security section. This is the designated area where users can set up their authentication methods, manage recovery codes, and manage their security features.

Project settings, repository settings, and CI/CD settings are geared towards managing different aspects of projects and deployment processes rather than user authentication. Therefore, while they are essential for other administrative functions within GitLab, they do not provide options for enabling two-factor authentication. The user profile settings within the Security section is specifically designed for managing personal security configurations, making it the correct choice for enabling 2FA.
