MacOS – How to get iCloud Two-Factor Authentication to work? (cannot turn on to begin using)

icloudmacospreferencesSecuritytwo-step-authentication

I click 'Continue', then 'Continue' for the 'Turn On' Radio button, a loading icon rotates for several seconds, then I'm back at step 1 and nothing appears to have happened.

Is bluetooth tethering 4G too slow an Internet connection for this feature to function? Is there a server connection problem so that I must use a different Internet connection? What is the problem?

Two days ago, on Wi-Fi, I tried and instead was getting a six digit code to enter, but despite entering it properly, was told to try entering it again. Both SMS and phone call six-digit code gave the same error, 'try entering it again'. Now I'm not even getting to that step. What is the problem? What is the solution?

You need to go to www.appleid.com (or www.myappleid.com) and sign in to your account. If you can get in, there you'll be able to enable or disable Two Factor Authentication. If you want it on, turn it off then enable it again (if it was on).

Make sure you delete any devices you no longer have while you are on that web site (near the bottom). It'll make things easier for you, especially with Two Factor Authentication.

If you do this and you find that you are still having issues, call Apple Support and they will investigate your account and see why you are still having issues.
