There are two events here:
First , login the http://hotmail.com where the APP [one of the three , twice verify methods] working alright from the device approved.
Second, windows 10 left Microsoft flag , click brought up settings \ account \ add \... its here Twice.Verify , just not response any code to on the device to be verified? Well,
the text , and email verifying done that added an account @Hotmail.com to windows 10 as one of verifying ID approaches ?
How this could be, afraid the three verify ways , beyond of mine , each of them can be configured on to divided a least three mac addresses ?
Best Attentions and highly Appreciated
