Security experts keep advising us to create strong and complex passwords to protect our online accounts and data from savvy cyber-criminals. And “complex” typically means using lowercase and uppercase characters, numbers and even special symbols. But complexity by itself can still open your password to cracking if it doesn’t contain enough characters, according to research by security firm Hive Systems.
As described in a recent report, Hive found that an 8-character complex password could be cracked in just 39 minutes if the attacker were to take advantage of the latest graphics processing technology. A seven-character complex password could be cracked in 31 seconds, while one with six or fewer characters could be cracked instantly. Shorter passwords with only one or two character types, such as only numbers or lowercase letters, or only numbers and letters, would take just minutes to crack.
