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.

Small Authentication 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.

Authentication Prompt with Outdated Software Notification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.

Your administrator may also choose to block access from certain computer and mobile operating systems. In this case, you must upgrade your OS to an allowed version or switch to a different device.
