iOS 7.0.3 brings back iCloud Keychain for all iOS and Mac devices. The story of why Apple removed the feature in iOS 7.0.2 and why it re-introduced it now can probably be summarized as a bug/perfection but let's keep that narrative for a later post. In this one, let's see how you setup and use iCloud Keychain across all your connected iOS devices.
iCloud Keychain, for the uninitiated, is the feature in iOS 7 that enables users to store their user passwords on iCloud. This means a password you use and store on iPhone can be used on your iPad too, provided it's connected to the iCloud account.
How to Setup & Use iCloud Keychain on iPhone, iPad, and iPod Touch
Step #1. Open the Settings app (on your iPhone/iPad.)
Step #2. Tap on iCloud.
Step #3. Scroll down and tap on Keychain.
Step #4. Turn the “iCloud Keychain” switch ON.
Step #5. You have two options: Approve from other device/Use iCloud Security Code.
Step #6. If you select “Approve from other device”, you will be asked to choose one of the other iCloud-connected devices. Then, use that (selected) device to enter the password for your iCloud account. This will switch ON iCloud Keychain on your first device.
Step #7. If you select “Use iCloud Security Code” – which is a simpler, easier option – you will be prompted to create a new iCloud Security Code. (4-digit PIN that is different from your passcode)
Once you have setup your first device, you should be ready to setup other devices. For instance, setup your iPhone for iCloud Keychain and then switch on the same for your iPad, iPod Touch or other iPhones in your home.
iCloud Keychain's philosophy is to help you use passwords securely across all devices. It's basically ‘auto-fill and remember password' for multiple devices. When you have stored passwords in Safari (and even credit cards), all this data gets synced to other devices.
So, when you store a username/password in Safari on iPhone, the same can be used on the iPad automatically.
iCloud Keychain also works for other passwords like your Wi-Fi. Pretty neat, huh?
