Duo Multi-Factor Authentication (Duo MFA)

Available To

Campus Faculty and Staff

Service Overview

Duo Multi-Factor Authentication  (also referred to as two-factor or two-step verification) adds a second layer of security to your login.  Multi-Factor Authentication means that when you log into certain campus applications, you provide two proofs of your identity.  At CSULB, that means entering your full email address and password plus using authentication services provided by Duo Security, a company that provides Multi-Factor Authentication service to some CSU campuses.

Verifying your identity using a second factor prevents anyone but you from logging in, even if they know your password.  A Two-Step Verification method is stronger than a password alone because two factors confirm that you are who you say you are:  something you know (your password) and something you have (a mobile device or hardware token).
