Convenience-Plus-Safety on a Phone

This is an enhancement request, unless there's a way to do it already. On a phone, I'd like a way to open 1Password using Face ID PLUS a simple code. Typing my entire 1Password password on a phone is too onerous, but with Face ID alone I'm concerned that in an attack situation the attacker might be able to aim the stolen phone at me and open 1Password before taking off. Requiring a simple code in addition to Face ID would protect against this while still keeping the use of 1Password on a phone convenient. Of course, this code could never be used by itself--only in conjunction with Face ID.

What do you think? And/or is the another approach to achieve the same convenience-plus-safety on a phone?

Thanks.
