Web APIs for delightful two factor auth experiences

It's a common practice to verify a phone number or implement two factor authentication by sending a one time password over SMS. We can all agree that it's a pretty terrible user experience though.


This process may increase security, but the friction can decrease conversion and the user experience in general. Android and iOS have APIs to combat this, so why not the web? In this talk we'll take a look at autocomplete and the WebOTP API to see how the web platform can help us build secure flows and a better experience all round.
