Feature Request: Unlock 1Password for iOS using a custom PIN and not the device passcode

Adding an optional, extra passcode requirement.

Why? Because inputting a long password/passphrase on the iPhone is too hard and using FaceID is too easy.

I've got a nice long password, which, of course, is a pain to enter on my iPhone. I know about using FaceID but feel uncomfortable about the fact that someone in possession of both my phone and me, could unlock 1Password very easily. Of course, using the iPhone's passcode alone is not too secure.

As a suggestion, I'd like it if there was an option to require a numeric passcode (not the iPhone's passcode) after the FaceID was passed, as an additional feature for the insecure, like me.

Thanks.
