Re: MFA without a Cellphone
cpbowcpbow The Authenticator app doesn't require or need any form of network connection if you select the OTP (Code method). Once registered to the user account - it constantly generates codes every 30 seconds or so based on an algorithm or seed which was linked with Azure at time of registration. So when a webpage displays "Enter the Code from your Authenticator" type message - it already knows what the correct code should be - and if you type in the correct code shown in the app - then you get access. The App itself doesn't need to transmit that code to Azure.
