In the past few months, we’ve been working on making our Duo Authentication Prompt more accessible to our users. We’re aligning to the Web Content Accessibility Guidelines (WCAG) 2.0, the most widely used set of standards for creating accessible websites. It’s based on 4 principles: that sites are perceivable, operable, understandable and robust. There’s various success criteria for these principles, and specific techniques that can be used to meet them. Many of the techniques are straightforward and simple, but there were some problems we ran into where there was not a clear answer, and we needed to get creative.
