Things About Two-Factor Authentication for Your Apple ID

--Wednesday, Dec.14, 2016

For most iOS users, Two-Step Verification is no more a new world. It has been offered on iPhone, iPad, iPod, Mac for years, which will prompts you to enter a four-digit code under the following circumstances:

1. Sign in your iCloud account on a new device.

2. Purchase something from one of Apple's stores on a new device.

3. Make changes to your Apple ID. 

The four-digit code will be delivered by push notification to a trusted device of your choosing, or via SMS text message. However, Two-Factor Authentication is a newer improvement upon Two-Step Verification, rolling out with iOS 9 last year. It's now available on the following devices:

  • iPhone, iPad, or iPod touch with iOS 9

  • Mac with OS X El Capitan and iTunes 12.3

  • Apple Watch with watch OS 2

  • Apple TV (4th generation) with TV OS

  • Windows PC with iCloud for Windows 5 and iTunes 12.3.3

Part 1: What is Two-Factor Authentication?

Two-Factor Authentication is the best way to keep your account secure, protecting your account even if someone has found out your password. The newer Two-Factor Authentication is an improvement upon that process. While the principle is similar, the execution is refined.

The verification code is nowsix digitsand is automatically sent to all of your authorized devices. When a new device is logged into your iCloud account, you're also shown the rough location of that device (on a city level), so that you can be sure it's not someone halfway around the world trying to gain access; there are also buttons to allow or deny that login.

Authentication only happens when you log into your iCloud account from a new device for the first time, or when logging into an account on the web. (In the latter case, you can choose to trust your browser so you don't have to do that every time.)

Note that some features in iOS 10 require two-factor authentication.

Part 2: How Does Two-Factor Authentication Work?

Two-Factor Authentication is an extra layer of security for your Apple ID designed to ensure all the photos, documents, and other important information you store with Apple can be accessed only by you, and only with your devices.

When you enter your Apple ID and Password for the first time on a new device, you'll need to provide two pieces of information—your password and the six-digit verification code. This code is displayed automatically on your other devices or sent to a phone number you trust. Just enter the code in order to sign in and access your information on your new device.

By entering the code, you're verifying that you trust the new device. For instance, if you have an iPhone 7 and are signing into your account on a newly purchased Mac for the first time, you'll be prompted to enter your password and the verification code for the authentication.

Once signed in, you won't be prompted for a verification code again on that device unless you sign out completely, erase your device, or need to change your password for security reasons.

Part 3: 6 Things About Two-Factor Authentication You Must Know

1. Remember All the Passcode

When you have Two-Factor Authentication for your Apple ID, you'll always need at least two of the following to sign in:

  • Your Apple ID password

  • Access to one of your trusted devices

  • Your Recovery Key

When you set up password or Recovery Key, please keep them in mind. Never do it when you're being distracted or in a bad mood. Currently, you will need to enter those passwords when log in your Apple ID on website, on a new device or make changes to your account.

2. Write down Passcords

With the development of technologies, there are many things involved with a password, like novel apps. We've set up quite a lot of different passwords for access to iPhone, WhatsApp, Facebook and so on, making us drown in an ocean of passwords. If you're afraid that you cannot recall passwords when they're needed, you'd better write down and keep them somewhere you can easily access. Also, you should have copies for them. You'll never know when mothers will come in and clean up our chaotic bedroom.

3. Set up a Complicated Password

I'm sure there are lots of people using the birthday of theirs or that of their loved ones as the password of different apps. Though it's easy to remember, it's in fact not recommended at all, for it's as well easy for others to decipher your password. Therefore, it's suggested to complicate your password with upper/lower cases or special numeric.

4. Make Your Screen Passcode Easy to Remember

Since people are used to Touch ID feature, using fingerprint to unlock and access the device, it's a commonplace that people forget the original password they've set up. Note that you cannot use Touch ID but fingerprint in some cases, likes the device reboots, or the device is being unoccupied after 48 hours. Therefore, though the passcord should be intricate, it should be easy for you to remember as well. Also, keep it different from other passwords. You can set up it as 'diA3s4' containing upper/lower letters and numbers.

5.Turn off "Show Previews" for Messages

For those who would like to check out SMS with previews, it becomes less convenient if turning off the "Show Preview" feature. However, whether it's for your privacy or security, it's recommended to disable this feature. You can turn it off by going to "Settings" > "Notifications" > "Messages", scrolling down to the bottom and toggling off "Show Previews".

6. Set up SIM PIN

Similar to the sixth one, to set SIM PIN is for improving the security of your privacy. Though you can stop others from previewing messages when the screen is locked, it's still possible to be viewed if someone takes out your SIM card and plugs it into another handset. However, you can prevent it via SIM PIN. Go to "Settings" > "Phone" > "SIM PIN". Toggle the bar on and you will be prompted to enter PIN to SIM card with a passcord of up-to-eight characters.
