password lockouts
Sunday, May 11th, 2008Has anyone ever stopped to ask themselves why they set password lockouts to 3 or 5? (The so-called “industry standard”). There are plenty of people who accidentally lock themselves out in 3 or 5 tried, and end up having to call the helpdesk (or equivalent) for a password reset. If the limits were raised to 10 or 20, it would probably greatly reduce those calls.
Generally passwords are much easier to obtain through human factors than brute force attacks. No additional security is gained by lowering the lockout from 20 to 3 as 20 attempts is still not enough to break in a brute force attack, and any password that can be guessed in 20 attempts can just as easily be guessed in 3.
