Turn on iCloud Keychain on your iPhone, iPad, or iPod touch
How to turn on iCloud Keychain
One of the great things about iCloud Keychain is that it suggests long, complex passwords for you when you first need to create one. If you allow iCloud Keychain to create your passwords and store them, you will be leaps and bounds ahead of everyone else. And this really is a game of being ahead of the pack.
Technically, iCloud Keychain is highly secure: Keychain passwords and credit card numbers are encrypted with 256-bit AES (Advanced Encryption Standard). End to end encryption — your data is protected with a unique (device) key and your device passcode, which only you know. Two-factor authentication is also recommended.
Tap Settings, tap [your name] and then choose iCloud. Tap Keychain. Turn on iCloud Keychain. You may be asked for your passcode or Apple ID password.
Step 1: How to turn on Keychain
iCloud is a pretty robust service with many different features — one of those is a built-in password manager called Keychain. That's right, instead of paying for a separate service like 1Password or LastPass, you can just turn on this feature inside the service you're likely already for paying for.
iCloud Keychain keeps the website login information and credit card information that you use with autofill in Safari, and your Wi-Fi network information up to date across all your Mac computers (OS X 10.9 or later), iOS devices (iOS 7.0. 3 or later), and iPadOS devices.
Like most Apple products, iCloud is known for being highly secure. Unfortunately, however, this doesn't mean that individual accounts cannot be hacked. In order to achieve this, all anybody really has to do is figure out your password. And if you're not careful, this isn't necessarily a difficult task.
Log in to the website and follow the directions to change your password. Tap Choose My Own Password, or tap Use Strong Password, and Apple will generate one for you. Tap Save to change your password to the one you created or Apple's strong password. If prompted, tap Update Password to save it to your Keychain.
If you're setting up on your Mac:
To use iCloud Keychain in Safari on a Mac, choose Safari > Preferences, click AutoFill, and make sure all desired categories are selected. On an iOS device, tap Settings > Safari > Passwords & AutoFill, and enable your preferred categories.
