Using the Duo Prompt

The Duo Prompt lets you choose how to verify your identity each time you log in.

Supported Browsers: Chrome, Firefox, Safari, and Edge.

Duo Prompt

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

Select Device in Duo Prompt

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

Method Description
Duo Push Pushes a login request to your phone or tablet (if you have Duo Mobile installed and activated on your iOS, Android, or Windows Phone device). Just review the request and tap Approve to log in.
Enter a Passcode

Log in using a passcode, either generated with Duo Mobile, generated by your hardware token (YubiKey), or provided by an administrator.

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

You can also use security keys for authentication.

Your Duo administrator may have limited which authentication methods you can use to log in. If this is the case, then the Duo prompt shows only the allowed methods. So, if your organization disallows phone call for Duo logins, the prompt may only show the "Send Me a Push" and "Enter a Passcode" options.

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 your organization has enabled self-service you can add an additional authentication device by clicking the Add a new device link, or update your setting and remove authentication methods by clicking My Settings & Devices.

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 Duo 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.

Small Duo Prompt

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 Duo Prompt.

Software Updates

You may be prompted to update outdated browser or plugin software when authenticating if your organization enabled this feature. You can take a few minutes to update your web browser, Flash, or Java version to the most recent before authenticating, or choose to update later and continue on to the protected resource.

Duo Prompt with Outdated Software Notification

If your organization blocks access to Duo-protected resources from devices with outdated browsers or plugins, then you may not complete two-factor authentication until you update your software.
