### Comment 2

One key feature of Duo Security is its strong two-factor authentication. It adds an additional layer of security to the login process by requiring users to verify their identity through a second factor, such as a push notification to a mobile device, a phone call, or a generated passcode. This helps prevent unauthorized access and enhances account security.
