I posted here too for my input: https://1password.community/discussion/comment/659797/#Comment_659797
I'd like to also add my dissatisfaction with the unlocking situation in 1Password 8. Advising people to use the same password for personal and work accounts is terrible advice. I'm a software/web developer and understand the ins and outs of secure coding, encryption and passwords.
Not everyone has Touch ID to enable multi-unlock, and no one should ever use the same master password for multiple accounts. This violates everything 1Password stands for. But having a regression in user experience like this and not listening to the feedback, claiming that you know better, is really disappointing. This helpful time-saving feature existed in several previous versions of the software.
At least you could provide it as an opt-in setting to allow one account (designated by the user) to unlock the others.
It's quite easy to implement as far as I'm concerned. One primary account password encrypts the passwords to the secondary accounts, and auto-unlocks them when you provide the primary password.
