Here are some tips that will allow you to take full advantage of the features in iCloud on your Mac and iOS devices.
With iCloud, you can get an @icloud.com email account that’s ad-free, is up to date everywhere you check it, and includes webmail at iCloud.com. Just select Mail in iCloud preferences and follow the onscreen instructions.
iCloud Keychain will generate and store all your Safari-based passwords and autofill them for you where and as needed. However, there may be times when a website doesn’t allow autofill (for example, at public terminals or shared computers).
iCloud Keychain keeps the following account information up to date across your Mac computers and iOS devices:
- Website account names and passwords that Safari autofills for you
- Credit card numbers and expiration dates that Safari autofills for you
- Most Wi-Fi network names and passwords
iCloud Keychain also keeps account names, passwords, and settings that you add to Internet Accounts preferences up to date on your Mac computers.
Passwords and credit card information are encrypted in your OS X keychain and your iCloud Keychain.
iCloud Keychain requires OS X v10.9 or later or iOS 7.0.3 or later.
Approve a device to use iCloud Keychain
If you set up iCloud Keychain on your Mac, and then you set it up on another device, you may receive a notification on this Mac asking if you want to let the other device use your iCloud Keychain.
Do one of the following:
- In the notification alert, click View, or
- In iCloud preferences, click Option to the right of Keychain, then click Details.

- Choose Apple menu > System Preferences, then click iCloud.
- Make sure Keychain is on and your Mac is approved.
- Click Options next to Keychain, then make changes in the dialog that appears
