When creating passwords to either access your files, software or even your devices, it is important not to fall into the trap of creating simple passwords that you’ll remember. While it is important to create passwords that are easy to remember, also be aware that a little bit of social engineering is enough to make a malicious individual easily crack your passwords. Passwords should be memorable for the user, but difficult for an attacker to guess.
