what is apple keychain

Apple Keychain is a password management system developed by Apple for macOS and iOS devices). It is designed to securely store and manage various types of data, including passwords, private keys, certificates, and secure notes). Keychain Access is the macOS app that allows users to view and manage their keychains. iCloud Keychain is a feature that works in collaboration with Keychain Access and allows users to share keychains with their other Apple devices. When a user accesses a website, email account, network server, or other password-protected item, they may be given the option to remember or save the password. If they choose to save the password, it is saved in their keychain so they don’t have to remember or type their password every time. Keychain Access securely stores and retrieves user names, passwords, and other information, making individual passwords more complex and difficult to break, which can make individual accounts more secure.
