When it comes to passwords, length is better than complexity.
Its a common myth that a short and complex password (Jfjfy&65^87) is more secure than a long and uncomplicated password (our awesome moon base rocks).
We recommend selecting a long, but easy to remember password such as our awesome moon base rocks which would take an estimated septillion years to crack as opposed to a complex one like Jfjfy&65^87 which would take just over 600 years on a standard computer.
