There are plenty of opportunities for friction in the user experience when logging in, particularly while entering a two factor authentication code. As developers we should be building applications that support the need for account security but don’t detract from the user experience. Sometimes it can feel as though these requirements are in a battle against each other.
In this post we will look at the humble
<input>element and the HTML attributes that will help speed up our users’ two factor authentication experience.…
Summary: simple changes like making your TOTP-receiving <input> to have
inputmode="numeric" gives user-agents solid hints about what kind of data is expected, allowing mobile phones to show a numeric keypad rather than a full keyboard, while
setting autocomplete="one-time-code" hints to password managers and autocomplete tools that what’s being collected needn’t be stored for future use as it’ll expire (and can
also help indicate to authenticators where they should auto-type).
As my current research project will show, the user experience of multifactor authentication is a barrier to entry for many users who might otherwise benefit from it. Let’s lower that barrier.
