Apple Two Factor Authentication: why verification code popup

by wellbeck190 / February 23, 2017 2:58 AM PST

I turned on Two Factory Authentication mode, it worked very well. But yesterday, I reinstalled my Macbook, and iPhone, verification code popup don't automatically display when I login new device. I must get code through text message, or manually getting verification code from iCloud setting. I logged both iPhone, and Macbook, but all don't show popup (I also try to log from another pc but same result).

I’m using Mac OS 10.12.3, and iOS 10.2.1

I think two cases:

1. It's a problem occurred when I reinstalled my device.
2. Someone (may be a "hacker") controlled my apple ID and my devices. (I'm worry about this)

Please, help me. Thanks!

You need to go in to and assigne your devices as "trusted" devices as well.

Then you should not ask me why, when using Apple two-factor authentication from i.e a Mac, the code pops up on the same Mac (as well as iPhone and iPad), sort of rendering it it pretty useless in case your mac (or iPad/iPhone is actually stolen. One would hope that the code would pop up on every device BUT the one where one tries to log in.

That said, your two best sites are always:

Never understood why Apple does not ponit everyone to those more often, especially the second one, over using often quirky iOS or Mac OS interfaces.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
