How to Make Your Passwords “Hack-Proof”

Experts say any password that's six characters or less can be cracked.

It may be time to change your password. A cyber security firm crunched some numbers and figured out how long it would take a hacker to crack any password. They say any password that’s six characters or less can be cracked instantly now, even if it’s got special characters. In general, it takes at least 12 characters to be somewhat secure. Or, go big…an 18-character-long password with numbers, letters, and special characters would take 438 trillion years to hack.
