> In 1Password 4 there is a brilliant new section called Security Audit. In the sidebar it shows you tabs for finding weak passwords, duplicate passwords, and old passwords.
> Clicking on the Duplicate Passwords tab gives you a list with every single login item that has a duplicate password. If you have any items here then you can begin working your way through each account, by logging in to the site and changing your password with a new unique one and saving that into 1Password.
Woah. I was in the beta and I never even noticed this. I am going to have to do this as a weekend project.
