Keychain is the password management system in macOS, developed by Apple.
With iCloud Keychain, you can keep your passwords and other secure information updated across your devices. iCloud Keychain remembers things, so that you don't have to. It auto-fills your information—like your Safari usernames and passwords, credit cards, and Wi-Fi passwords on any device that you approve.
