choosing a second factor
Smartphone + Duo App
The preferred method (and the most convenient) is the Smartphone + Duo App option. This involves you installing the Duo app on your iPhone or Android smartphone.
How it Works
When you're prompted to enter your Duo passcode on your computer, click "Send Me a Push" and you'll be prompted on your smartphone. Simply confirm that you're logging in by clicking "Approve" and you're done.
Text Message SMS
Using the text messaging option as a second factor is convenient in that you are simply texted a passcode to your smartphone.
How it Works
When you're prompted to enter your Duo passcode on your computer, you'll need to click "Enter a Passcode", then "Text me new codes" . Simply confirm that you're logging in by typing the passcode in the dialogue box on your computer.
Hardware Token
A hardware token is a small device, similar to a fob that you might see to unlock your car. It has a digital display that shows a passcode that can be used as your second login factor.
How it Works
When you're prompted to enter your Duo passcode on your computer, you'll need to click "Enter a Passcode", then from your hardware token, press to generate a new code. Simply type the passcode in the dialogue box on your computer.
To request a hardware token, please contact the IT Help Desk. IT will provide one initial hardware token per employee upon request.
Touch ID
Touch ID is only available for MacBooks with Touch ID enabled.
How it Works
When you're prompted to enter your Duo passcode on your computer, you'll be able to use your existing Touch ID factor (e.g. your fingerprint) to allow access on your Mac.
Security Key
A security key is a separate device that plugs into our USB port.
How it Works
When pressed or tapped upon your Duo login prompt, the key sends a signal to Duo to permit the login. This is a hardware key that plugs into a USB port on your computer. Only certain keys are supported. Please contact the IT Help Desk for the current vendor and supported device list. Hardware keys may be purchased by university departments, but will not be available through Information Technology. Hardware keys do not require IT to program and may be self-enrolled through the Duo prompt when logging in.
