The folks over at Lifehacker have found another great site for us to talk about.
How Secure Is My Password is a no-frills password checker that dishes the dirt on your password strength or lack there of.
How Secure Is My Password is a simple site with a singular focus, forcing you to think about the strength of your passwords. Enter any string of characters and it will tell you how long a brute force attack against that password would take using modern computers.
NOTE: For the sake of security, we'd strongly recommend constructing fake passwords for testing purposes rather than using your actual password. Consider the site an interesting exercise about how adding a few characters and symbols to your password can increase its security. You can never be too paranoid about security!
Simple passwords like "Password" are immediately flagged as weak, identified as one of the most 500 common passwords. Plug in something a little trickier like RedDogLa$er4225#Niner and you get a nice comforting response "It would take about 7 septillion years for a desktop PC to crack your password".
