I like the "warnings" in Sticky Password Pro 6 beta, and I'm assuming that they are just logins with insecure passwords.
With the rate of website passwords being leaked, would it be an option to flag passwords that are regularly used? Possibly with a future feature of a "Uniqueness" option on the More button, showing accounts with passwords bearing a resemblance to the selected account.
eg Select the PSN account, chose Uniqueness from the More menu, and have it flag the xbox account that has only one character difference.
I realise it is a little late in the Beta to have extra options added to the More menu, but could the regularity of a password be added to the warning or insecurity test?
