Two-Factor authentication for Apple ID in Myanmar

Hi Van Bawi Thang,

Thank you for posting. I understand you might be running into some issues setting up two-factor authentication.

Can you clarify what happens when you try? If you're seeing an error, what does it say?

I see you've confirmed Availability of two-factor authentication for Apple ID in your region. Have you double-checked these requirements as well?

"Who can turn on two-factor authentication?

Two-factor authentication is available to iCloud and iTunes users with at least one device that's using the latest iOS or macOS. Here are the minimum recommended system requirements for all devices that you use with your Apple ID:

• iPhone, iPad, or iPod touch that uses a passcode, with iOS 9 and later 
• Mac with OS X El Capitan and iTunes 12.3 and later
• Apple Watch with watchOS 2 and later
• Apple TV HD with tvOS
• Windows PC with iCloud for Windows and iTunes 12.3.3 and later

We also recommend that you have a valid credit card on file in your account. This information may be requested to help verify your identity if you forget your password.

While most iCloud users can now turn on two-factor authentication, certain account types may still be ineligible at Apple’s discretion."

Hopefully this helps!

You are still using secondary authentication account ( in which three answers for security questions , date of birth , a rescue mail is added .

Click on edit and click on get started .

You have opened system preferences > iCloud > clicked on account details , enter the Apple ID and password ( for secondary authentication account ) , under security section > if you click on turn on two factor authentication , if you are trying to enter a new trusted number ( it has to be verified ) and updated in the account .
