"Researchers expose vulnerabilities of password managers":
Unfortunately this article is very vague.
I have seen posts on this forum that people which forget their password can try as many times as they want, so no limit (as mentioned as a weakness in this article). However, I don't think 1Password uses a PIN (only a Master Password) on desktop platforms. In fact, the article does not even mention on which platforms this happens...
Is 1Password affected?
