How to measure password strength?
How to use it?
Usage is very simple – you just type your password into the text box and page displays average time to crack it. If you are into numbers you can press SHow Details button to see length of the password, character combinations, calculations per second and number of possible combinations. Geeky stuff.
Underneath the result website displays some additional tips – following them can increase your password strength substantially, so it is worth reading this section!
Strength of the password is also indicated visually – page background changes the color from red (weak) to green (strong). Time needed to crack the password is given in the text form – it is interesting to see these huge numbers as text. I managed to create 198 characters password which would take “quintillion nonagintillion years” to crack. I am not even sure such number exist – it may be an author’s joke. If you want to check password strength against more powerful computers, you can change number of calculations per second in the Settings.
It is definitely worth checking strength of your password – it may spare you an unpleasant surprise.
