Duo helps keep information secure with software and operating system policies. Your Duo administrator may choose to warn you when your software is out of date, require software updates before allowing access, or even block access from devices that don't meet your organization's requirements.

Has your organization enabled the new Universal Prompt experience? See the Universal Prompt guide for more information. Duo Push in Universal Prompt

Software Update Notifications

If your Duo administrator has enabled this feature, we'll check your operating system and browser version — as well as the version of the Java and Flash plugins enabled in your browser — when you log into your Duo protected service. If any of them are out of date we'll let you know, and give you the option to update your software before you finish logging in to the service.

Updating Your Software

We'll tell you how to update your software and link to other vendors' download sites where applicable.

Updates for browsers built into the operating system, like Safari on macOS or Internet Explorer and Edge on Windows, are typically delivered using the system's built in software update service. Check Windows Update on a PC or Software Updates on a Mac to apply any outstanding security updates. For example, Windows 7 and later users using Internet Explorer versions older than Internet Explorer 11 have the opportunity to upgrade to version 11 via Windows Update.
