If you want to be really secure, you would make the user change the password after every use. However, that is unrealistic. You're dealing with users, who probably aren't as aware as we are of security. Users don't want to change their passwords often, because it breaks their habits, so I think 90 days, from the user's point, is acceptable. That being said, you should ensure that the new password isn't the same as the old password, and the new password isn't the same as the old password, except for a number at the end (password1 changes to password2, etc.). If the passwords are strong enough, you should be OK, imho. On Tue, 18 Feb 2003, Robert Sieber wrote:
It doesn't make sense because 90 days is too long. A password should be changed at least after 30 days - if they are strong enough. A cracker has 90 days to find out the correspondig password .....

We force our users to change their mail password every 90 days. Does this make sense? Why? -- ullmic
