Apple iCloud Keychain

iCloud Keychain is Apple's native password and passkey manager built into iOS, iPadOS, and macOS. It's free, deeply integrated, and offers seamless autofill across Apple devices. With Family Sharing, passwords can be shared among family members. Recent updates added 2FA code generation and support for physical security keys.

Its major limitations are its confinement to the Apple ecosystem (no dedicated Windows/Android app, only via browser extension) and lack of advanced features like secure notes or extensive password health reports. For families fully invested in Apple's ecosystem, it provides a convenient and secure baseline solution. For mixed-device households or power users, it's insufficient.
