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. For more information about WPA security keys, see What are the different wireless network security methods?
