Password, 123456, qwerty - while passwords which appear on the list of the most common passwords should definitely be retired from use, even a more unique password can be easy to crack if a computer program is tasked with systematically breaking it. As seen in data by website Security.org, adding even one upper case letter to a password can already dramatically alter its potential. In the case of an eight-character password, it can now be broken in 22 minutes instead of instantaneously in one second – an increase of more than 1000 percent.
