Multi-Factor Authentication (MFA)

Multi-factor authentication (MFA) is an access security product used to verify a user's identity at login. It adds two or more identity-checking steps to user logins by use of secure authentication tools. Adding MFA keeps your data secure. With Cisco Secure Access by Duo, it's easier than ever to integrate and use.
