HTML attributes to improve your users’ two factor authentication experience

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.

  name="token"
  id="token"
  inputmode="numeric"
  pattern="[0-9]*"
  autocomplete="one-time-code"
/>
