I’ve always thought that if someone gained the ability to surreptitiously capture my devices’ camera feed, I have bigger problems than just my image getting leaked or used as blackmail (because that would necessitate something blackmail-worthy). Also, they’ll get some pretty boring pictures. What else should I consider here?
It's hard to know what kind of information could leak in advance. It gives the attacker more information on your surrounding. They could take mug shots to craft a fake profile. Or maybe see a credit card flashing by... it doesn't have to be blackmail-worthy material necessarily.
Granted, if the attacker can access the webcam then most likely your system is compromised, 1password is compromised (including the 2nd factor as advertised on the site), so you might have bigger problems already. It all depends on the intent of the attacker.
I came here to write that exact comment. If I don't trust my computer to not be infected, I should not use it at all. Having someone watch me picking my nose is far less privacy-invading than someone accessing my photo library for example.
