Password security overview
iOS, iPadOS, macOS, and visionOS make it easy for users to authenticate to third-party apps and websites that use passwords. The best way to manage passwords is not to have to use one. Sign in with Apple lets users sign in to third-party apps and websites without having to create and manage an additional account or password while protecting the sign-in with their two-factor authentication for Apple Account. For sites that don’t support Sign in with Apple, the Automatic Strong Password feature enable a user’s devices to automatically create, sync, and enter unique strong passwords for sites and apps. On iPhone, iPad, and Apple Vision Pro, passwords are saved to a special Password AutoFill keychain that’s user controlled and manageable by going to Settings > Passwords.
On a Mac, saved passwords can be managed in Safari Passwords preferences. This sync system can also be used to sync passwords that are manually created by the user.
