A WPA2 passphrase is a password that secures your home Wi-Fi network from unauthorized access. It is essentially the same thing as a Wi-Fi password and is considered one of the safest forms of Wi-Fi protection. The WPA2 passphrase is not the same as the password for the access point, which lets you access the access point settings. The WPA2 passphrase allows printers and computers to join your wireless network. You can usually find your WPA2 passphrase in your router’s security settings and will be asked for a new passphrase when setting up your home network. The person who set up your network usually keeps the WPA2 passphrase, so you may need to contact your system support person if you cannot find it.
