1. How does iCloud Keychain work?

As mentioned above, iCloud Keychain will help us confine security information between devices in Apple's ecosystem, between OS X and OS X, iOS with iOS and of course iOS with OS X. The contents that iCloud Keychain supports include:

1. Login information to the website
2. Credit card information
3. Wi-Fi network name and password
4. User account information (Mail, Contacts, Calendar, Accounts iMessage, Twitter, Linked In, Facebook .).

In addition, iCloud Keychain also supports creating passwords automatically when you register as a member of a website. This password is very complicated because it has TRF-7Z6-GH7-8IJ format, of course the iCloud Keychain will remember to help you and fill it out yourself so it still ensures safety.

The synchronization only takes place in devices that are logged in with an iCloud account, which means only your own devices, because you own it, it will be iCloud Keychain sync information through. If you are worried about security, Apple also has a 256-bit AES encryption mode, even when iCloud Keychain transmits information to the server when the data is stored on its server.

To enhance safety, Apple also uses the security code system iCloud Security Code and SMS authentication code to ensure that the device is properly enabled iCloud Keychain is yours. This part I will say more while guiding you to activate iCloud Keychain.

2. Why should I use iCloud Keychain?

With iCloud Keychain, this period is removed, when you disable Quantrimang on iOS devices, the login information will be automatically filled out by the data that iCloud Keychain transferred from the Mac. You just need to press the Sign in button again.

One more example, this is also very good. When you use an iOS device to access Wi-Fi in a certain cafe, the next time you come and open the Mac computer, the device will access the hotspot automatically and you don't need to manually enter the password again. half.

Compared to other password managers, such as LastPass or 1Password, iCloud Keychain is tightly integrated with the operating system and make sure that it runs, no need to sit and think about it, when should I run this feature .

Of course, iCloud Keychain also has drawbacks, it is only running well in Apple ecosystem. If you use Android or a Windows computer, the iCloud Keychain is completely useless, simply because these two operating systems do not support iCloud. Besides, using iCloud Keychain for third-party apps is not easy because it depends on whether the developer integrates it for his product or not. Currently popular OS X and iOS apps do not play with iCloud Keychain.
