Supported Browsers: Chrome, Firefox, Safari, Edge, Opera, and Internet Explorer 8 or later. Some browsers do not support all of Duo's authentication devices (for example, Security Keys won't work with Internet Explorer). For the widest compatibility with Duo's authentication methods, we recommend recent versions of Chrome and Firefox.
