A password is your first and last line of defense in computer security. Typically people choose bad passwords because they are easy to remember. However, you wouldn’t leave the door to your home unlocked because it is too much of a hassle to unlock it before you open the door, would you? A weak password is the same thing.
Using words that appear in a dictionary, in any language, make cracking your password that much easier. Adding numbers to dictionary words doesn’t increase the password’s strength at all if it is based on a dictionary word. Even with character replacements like capital letters and non-alphanumeric symbols, you’re not getting a stronger password.
A true strong password should consist of 7 or more characters and be part of a “passphrase”. A passphrase consists of a phrase that has special meaning to you, therefore making it easier to remember. For example:
Mickey Mouse for President. It would be awesome!
One simple approach to create a better password is to take the first letter of each word in your passphrase.
