Nick, no, it doesn’t help. By the definition of multiple-user support that you’re using, I could also share a single email address, like firstname.lastname@example.org, but almost anyone would consider that cringeworthy. Multiple humans sharing a single set of credentials is not what this thread is talking about. If multiple users each want to use strong passwords and their own password managers, they don’t want to be emailing around passwords in plaintext, and they each want to deal with lost-password recovery on their own, then the hack you’re describing isn’t sufficient.
We train users not to share login credentials. Pretending that sharing is the same as multi-user support is disingenuous.
I understand that this thread (as well as others going back more than a year now) is asking for engineering work. We’d like the user-profile table to be distinct from the camera-system table. We’d like it to be a many-to-many relationship. Amazon (your company) lets multiple users (real users, not pretend users) share a single Prime account. Where there are business reasons to restrict multiple-user access, such as Kindle book purchases, they don’t support it, and I understand that. But there are ample business reasons for Blink to support true multi-user access to a single system.
You’re a security company. A security company shouldn’t encourage people to share passwords.
