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 devices) prevents anyone but you from logging in, even if they know your password. Indiana Tech leverages DUO for its MFA platform.
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 log in as usual with your username and password, and then use your device to verify that it’s you. Your administrator can set up the system to do this via SMS, voice call, one-time passcode, the Duo Mobile smartphone app, 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.

Why is push the best authentication method?
It’s quicker than a text or a phone call
- Authenticating through a text message requires waiting to receive the text, reading a passcode, and then typing in the appropriate characters
- Phone calls require actually answering the phone, listening to the recording, and using the dial pad to approve the login.
- Duo Push is as simple as approving a notification on your smartphone.
It’s more secure
- Duo Push uses cutting-edge end-to-end encryption that SMS and phone calls can’t.
- The Duo Push screen displays detailed information about the application and source device that initiated the authentication request.
How Do I Set It Up?
Duo’s self-enrollment process makes it easy to register your device and install the mobile app (if necessary). Learn more about enrollment »
