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 Duo, it's easier than ever to integrate and use.

The Duo Multi-Factor Authentication Evaluation Guide

Not every MFA solution is the same. Some vendors only provide the bare minimum needed to meet compliance requirements — and include lots of hidden costs required for deployment, operation and maintenance. Plus, many traditional solutions are clunky and error-prone, and require extensive user training and support.
