Check your Password Strength with PasswordMeter [Cool links]
If you think your password is strong and cannot be easily guessed, think again. Because my current password that has 15 characters just scored 0% on the passwordmeter because it contains number only and a lot of repetition.
Passwordmeter contain several parameter to judge your password based on strength (character, number, symbol combination) and weakness (repetition, word only, number only). It’s a good start to create your password that cannot easily cracked, but don’t forget that you should remember your password as well.
And as for my password, i already change it to 9 character but scored amazing 100% and it easy to remember as well.
