See https://www.twilio.com/blog/html-attributes-two-factor-authentication-autocomplete#:~:text=In%20iOS%20and%20Safari%20on,code%22%20will%20trigger%20this%20behaviour we could use
autocomplete="one-time-code" for the 2FA form field.
See same blog re auto complete fields for passwords, repeat password, etc. Also explained in https://twitter.com/swyx/status/1280478276931031041
For emails and URL form fields for example we could set inputmode: https://twitter.com/IMAC2/status/1293863884537946112 . We already have
FieldConfig::UI_CONTROL_EMAIL and same for URL.
We could also see if we changed inputmode for numbers and set the type back to text see https://technology.blog.gov.uk/2020/02/24/why-the-gov-uk-design-system-team-changed-the-input-type-for-numbers/
