Reviewing discussion here:
i see that Master Password for first Team/Family account is used to unlock app - which is i guess reasonable, once app was logged into, you do not want to keep re-entering all Master Passwords.
This does imply to me that app encrypts and stores locally Master Passwords for accounts other than first one - please confirm my understanding.
I guess it's a design choice, but i did not find it in the "1Password Security Design" whitepaper.
There is nothing nefarious about it, and recovery (if this first account is disabled or master password is lost) is simple (as long as you remember other Master Passwords).
I'd rather have this done more transparently, with a warning to the user; and reflect which master password is required in the UI, if there is more than one - i.e. "Enter your Master Password (local)" vs "Enter your Master Password (Team BLAH)".
Thanks! Love 1Password, and want it to be better.
