Typically, users are prompted on a website to verify their identity by entering a PIN and interacting with a physical security key. This user-friendly flow is designed to to be fast, secure, and reduce reliance on passwords.</p> <p>But what if you need to implement this functionality outside of a browser? What if your application runs in a command-line interface (CLI)? The good news is this is possible, but it&rsquo;s not well documented or commonly implemented. I was motivated to implement this as leaving a terminal and waiting for a page to load to tap a device seemed wasteful.</p>
