With the amount of hacked accounts going on in here, why dont these forums implement users to change there pass every 1-3 months and have their original pass expire? I remember seeing this in blackhatworld, at first I was annoyed having to change the pass every so often but I didn't mind and I can see why they do this now. Too many folks like to use the same pass for every forums, what do you think?
Well, the main problem is that the security log is used to identify changed passwords, and this change is used to identify hacked/sold accounts and prevent users from getting scammed. Also, a lot of users don't log in for weeks/months, which might lead to forgotten passwords and lots of password reset requests for the admin.
Personally, i always encourage users to use a password manager (i use keypass), and generate a unique password per service.
