# Pin Input

The `Pin Input` field takes a numerical code, which can be used to complete the SMS verification process by entering a SMS verification code.

This field requires a Feathery auth integration to be turned on in order to integrate seamlessly, but you can also use this field to collect PINs for your own use.
