Duo Updating App, what's new in Duo?

Duo is releasing a redesigned version of its Duo Mobile app for iOS and Android the week of October 11. Duo Mobile 4.0.0 will provide the same security and functionality while offering an enhanced mobile experience.

What's New in Duo Mobile 4.0.0

Beginning the week of October 11, users will experience a new "push" authentication screen on their registered device. Instead of a red square on the bottom right to “Deny” and a green square on the bottom left to “Approve,” there will be a green "Approve" circle on the right and a red "Deny" circle on the left. A side-by-side visual of this change is available below.

The app’s accessibility features will improve, including a responsive design that allows a landscape view and compatibility with device-level accessibility settings, allowing variable font sizes and improved color contrast.
