iCloud Keychain

iCloud Keychain is a secure Apple service that stores and automatically fills in your passwords, credit card details, and Wi-Fi network information across your Apple devices. It uses strong encryption to protect this data, ensuring only you can access it. When you log into websites or apps, iCloud Keychain can suggest and fill in your saved information, making it easier and faster to access your accounts while maintaining security. It helps you manage multiple passwords without needing to remember each one individually, keeping your online activities convenient and secure.
