In this article, you’ll learn more about iCloud Keychain, how to use it, and its best uses.

What is iCloud Keychain?

Apple’s iCloud Keychain offers one secure location to save personal information. Perhaps most importantly, it remembers this information so you can auto-fill content across the web and apps such as usernames/passwords, credit cards, and social log-ins. You can use iCloud Keychain to store Wi-Fi passwords and credit card information. iCloud Keychain information is protected with end-to-end encryption, Apple’s highest level of security. Your data is protected with a key stored on your device, combined with your device passcode. Without these two pieces, no one can access this data, including Apple. iCloud Keychain is turned on during the setup process on each Apple device. If you didn’t activate the tool during setup, you could do so later at any time across your Apple devices.

How to Turn On iCloud Keychain: iPhone and iPad

On your mobile device:

Tap the Settings app on your Home screen.Choose your name at the top of the device.Select iCloud.Tap Keychain.Toggle ON Keychain.Follow any additional directions you may have, depending on your device.

How to Turn On iCloud Keychain: Mac

Click the Apple icon at the top left of your Mac screen.Choose System Preferences.Select Apple ID.Toggle ON Keychain under iCloud.Follow any additional directions you may have, depending on your device.

Generating Passwords

The No. 1 reason to use iCloud Keychain is to store usernames/passwords for websites and apps, when applicable. Doing this is slightly different, depending on your device. The information is stored in the same location, regardless of where the combination gets used, making sense when you better understand how it works. For example, let’s say you create a username/password on the New Balance app on iPhone. Once saved to iCloud Keychain, that combination is also used on the New Balance website on Safari. Better still, the tool knows this and will recommend the combination accordingly.

About Strong Passwords

When you create a new password through Safari or an app, you’ll notice a choice to Use a Strong Password. When selected, Apple auto-generates a password that includes eight or more characters, upper and lowercase letters, and at least a number. Sometimes a website or app doesn’t allow this combination. In those cases, you’ll need to create a password that matches the individual requirements.

Creating a Username/Password – Safari

The following directions work on the Apple Safari app, regardless of your device.

Create a new account on the website you’re visiting.Tap Use Strong Password or create your own password.

Using Username/Password Through an App

Once you’ve created your personal information through the web, you can use it to authentic your account on the company’s website, when applicable.

Tap Log In in the app.Tap Passwords in the box.Take the username/password combination under Suggested Passwords.Accept the combination in the app.

Note: iCloud Keychain isn’t perfect; occasionally, usernames/passwords created in one location won’t carry over. In those cases, you’ll have to add them manually.

Managed Your Saved Passwords, Other Information

You can find a running list of your saved iCloud Keychain information in both Safari (on Mac) and the Settings app (on iPhone and iPad). You can update or delete this information at any time. When you do, the changes sync across the rest of your devices.

To Find iCloud Keychain Information on Mac

Open the Safari app on your Mac.Choose Safari > Preferences on the left side of your Mac toolbar at the top.Click the Password tab. Log in using your system password.

From here:

Use Search to find the website you’d like to review.Highlight the website you wish to check.Choose Details to view the website username and password.Make changes, as applicable.Select Delete to remove the website information or Add to add new website information.

What About Credit Cards?

When you add credit or bank card information on a website or app, iCloud Keychain will suggest saving the information for later use. When you do, you’ll receive a prompt to use that information when attempting to make a purchase elsewhere. Again, this only works on the Apple Safari website and apps. iCloud Keychain will automatically add your card number and expiration date. However, you’ll need to add the 3- or 4-digit security code every time.

To Adjust Banking Card Information

You can change or delete bank or credit card information on iCloud Keychain through Safari and iPhone/iPad. On Safari on Mach:

Open the Safari app on your Mac.Choose Safari > Preferences on the left side of your Mac toolbar at the top.Click the Autofill tab. Log in using your system password.Choose Edit next to Credit cards.Select Add to add a new bank card.Highlight the card you wish to delete, then click Delete.

On the iPhone or iPad:
