|Tips for creating strong passwords|
A password is a string of characters used to access information or a computer. Passphrases are typically longer than passwords, for added security, and contain multiple words that create a phrase. Passwords and passphrases help prevent unauthorized people from accessing files, programs, and other resources. When you create a password or passphrase, you should make it strong, which means it's difficult to guess or crack. It's a good idea to use strong passwords on all user accounts on your computer. If you're using a workplace network, your network administrator might require you to use a strong password.
In wireless networking, a Wi?Fi Protected Access (WPA) security key supports the use of a passphrase. This passphrase is converted into a key that is used for encryption, which is not visible to you.

H3ll0 2 U! is a stronger alternative because it replaces some of the letters in the complete word with numbers and also includes spaces.
Help yourself remember your strong password or passphrase by following these tips:
If you feel you must write down your password or passphrase to remember it, make sure you don't label it as such, and keep it in a safe place.
