Use iCloud Keychain to keep passwords, accounts, and more up to date with iCloud
With iCloud Keychain, you can securely store your passwords, accounts, and more in iCloud, and access them on all your devices.
Access the same passwords, accounts, and more on all your devices
When you set up iCloud Keychain, your important information is stored in the cloud, which frees up space on your device. iCloud Keychain uses industry-standard technologies, like end-to-end encryption, to keep the following information secure:
-
Safari user names and passwords
Passkeys
Credit card numbers and expiration dates
Wi-Fi and AirPlay passwords
The accounts you use in Mail, Contacts, Calendar, and Messages
Because your information is stored in the cloud, you can access it anywhere that’s set up for iCloud Keychain, including your iPhone, iPad, and Mac. You can also access web passwords on a Windows device when you turn on iCloud Passwords in iCloud for Windows.
Changes you make on one device—like updating a Safari user name, changing a password, or deleting an account—automatically appear on all your devices. Your information is always up to date, no matter where you access it.
Share your passwords, accounts, and more with others
With iOS 17, iPadOS 17, macOS 14, or later, you can share passwords and passkeys with a group of trusted contacts. Everyone in the group can add and edit passwords to keep them up to date. Because sharing is through iCloud Keychain, it’s end-to-end encrypted. With iOS 18, iPadOS 18, macOS Sequoia, or later, you can also share your Sign in with Apple accounts, so everyone in the group can quickly and privately sign in to apps and websites.
See “Share passwords or passkeys with people you trust” in the user guide for iPhone or iPad, or the Passwords User Guide for Mac.
Note: If you move a password into a shared group, you can only access the password on device with iOS 17, iPadOS 17, macOS 14, or later.
