What is Two-Factor Authentication?

Two-factor authentication adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.

How It Works

• Enter username and password as usual
• Use your phone to verify your identity
• Securely logged in

Once you've enrolled in Duo you're ready to go: You'll login as usual with your APIC username and password, and then use your device to verify that it's you. APIC IT administrator can set up the system to do this via the Duo Mobile smartphone app push (recommended, default), SMS, voice call, one-time passcode, and so on.

Why Do I Need This?

Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked — you might not even know someone is accessing your account.

Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. With Duo Push, you'll be alerted right away (on your phone) if someone is trying to log in as you.

This second factor of authentication is separate and independent from your username and password — Duo never sees your password.
