Dan-cer I think the issue is not to enter the wrong pin, but to accidentally unlock the wrong profile (e.g. I want to go to my banking profile and assume that's the last one I was on, but happen to log in to my owner profile instead).
There are good use cases for using different pins or security settings btw., e.g. if you are okay sharing a specific profile with your partner or use one less sensitive profile in places where people or cameras can spot your pin.
navtis The other thing that strikes me is that it would be useful to be able to change the entry method for profiles depending on the threat model.
Not exactly perfect for what you are asking for, but to my knowledge the lockscreen security settings are independent in each profile. You could allow fingerprint unlock in one, long passkeys in the second and no protection at all in a third profile (not advised). This will make it easier to unlock lower threat model profiles without compromising the security of other profiles.
The method of switching profiles will remain the same though, and I assume it can't be automated since that might increase your attack surface.
