Two Step Verification on several devices
HI.
I Have an iMac, iPad, and an iPhone.
In these devices there Are the same apps like iMessage and FaceTime.
When opened the IMac's FaceTime app I needed to add Two Step Verification
ok
but when opened the app in my iPhone, I need also to create two step verification again.
so do I need to create passwords in all devices?
Do I need to save the password somewhere?
Thanks
iMac, OS X Yosemite (10.10), Late 2012
