Set up iCloud Keychain

With iCloud Keychain, you can keep your passwords and other secure information updated across your devices.

iCloud Keychain remembers things, so that you don't have to. It autofills your information—like your Safari and app usernames and passwords, passkeys, credit card information and security codes, and Wi-Fi passwords on any device that you approve.

How to turn on iCloud Keychain

Before you turn on iCloud Keychain, update your device to the latest iOS or iPadOS, or the latest version of macOS, and turn on two-factor authentication for your Apple ID.

When you update your device, the setup assistant asks you to set up iCloud Keychain. If you want to set up iCloud Keychain at another time, follow these steps.

Turn on iCloud Keychain on your iPhone, iPad, or iPod touch

  1. Tap Settings, tap [your name], then choose iCloud.
  2. Tap Passwords and Keychain.*
  3. Turn on iCloud Keychain. You might be asked for your passcode or Apple ID password. 
    On iPhone, turn on iCloud Keychain in Settings

Turn on iCloud Keychain on your Mac

  1. Choose Apple menu  > System Settings (or System Preferences). 
  2. Click your name, then click iCloud. In earlier versions of macOS, click Apple ID, then click iCloud in the sidebar.
  3. Turn on Password & Keychain.*
  4. If you choose to "Approve Later" when signing in to your Apple ID, you need to approve with an old passcode or from another device when prompted. If you're unable to approve, reset your end-to-end encrypted data when prompted.

*On your iPhone, iPad, or iPod touch with iOS 13 or later, or on your Mac with macOS Catalina or later, two-factor authentication is required to turn on iCloud Keychain. If you haven't set it up yet, you're prompted to update to two-factor authentication.

If you turn off iCloud Keychain

When you turn off iCloud Keychain, password, passkey, and credit card information is stored locally on your device. If you sign out of iCloud on that device while Keychain is turned on, you're asked to keep or delete that information. 

  • If you choose to keep the information, it isn't deleted or updated when you make changes on other devices. 
  • If you don't keep the information on at least one device, your Keychain data is also deleted from the iCloud servers.

How iCloud Keychain protects your information

iCloud protects your information with end-to-end encryption, which provides the highest level of data security. Your data is protected with a key that's made from information unique to your device, and combined with your device passcode, which only you know. No one else can access or read this data, either in transit or storage.
