These items include passwords for email, websites, servers, Wi-Fi networks, network shares, encrypted disk images, secure notes, private keys, and certificates. The Keychain Access application stores a wide variety of items. Since Mac OS 8.6, the Mac has managed passwords with Keychain, Apple’s password-management system. Fortunately, your Mac can store these passwords and automatically fill them in when needed.

We now juggle dozens of passwords for accessing our iOS devices or logging on to our Macs. Keychain Access: The days when people had to memorize just one password are long gone.
