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

Hi Dave,

Many people who might see you regularly at work might know your iPhone passcode. Also children know our phone passcode. We don’t want either of these groups knowing how to access 1password.

Recent stories of phone being stolen with known passcodes is an also a major security threat I am concerned about. I'm sure most users and your team here will have heard of the news linked here.

I am requesting the unique PIN available in 1password 7 be re-instated in 1password 8.
