Using the Duo Authentication Prompt

How-To Login to the Duo Authentication Prompt

The authentication prompt lets you choose how to verify your identity each time you log in to Duo protected applications like My NetID.

Supported Browsers: Chrome, Firefox, Safari, Internet Explorer 11, Microsoft Edge, and Opera.

If you have more than one device enrolled you'll see a device selector.

Select the device you want to use and then choose your authentication method.

Call Me Authenticate via phone callback.
Duo Push Pushes a login request to your phone or tablet (if you have Duo Mobile installed and activated on your iPhone, Android, or BlackBerry device). Just review the request and tap Approve to log in.
Enter a Passcode

Log in using a passcode, either generated with Duo Mobile, sent via SMS, generated by your hardware token, or provided by an administrator.

Click Send codes to get a new batch of passcodes texted to your phone.


You can also use U2F Tokens for authentication.

If you can't authenticate or aren't sure what to do, click Need help? on the left side of the Duo prompt. Your administrator may have customized the help text with additional instructions or contact information.

Self-service Options

If available, you can add an additional authentication device by clicking the My Settings & Devices.

Trusted Devices

You'll also see a Remember me for... option if your administrator enabled Duo's trusted devices feature. If you check this box when authenticating you won't need to perform Duo second-factor authentication again for the duration specified on the prompt.

Authenticating from Smaller Screens

If you're logging in with Duo from a device with a smaller screen (like a tablet) or small browser window then your authentication prompt may look slightly different. Don't worry! All the devices and options shown in the full-size prompt are available for use, and you can enroll and manage devices by following the same steps.


Access Add a New Device or My Settings & Devices by clicking the Settings button at the top. Click the X on the Settings button to return to the authentication prompt.
