Hi,
Some members of my team keep failing to login on Microsoft Azure because the system does not send a notification of Two Factor Authentication on the Microsoft Authenticator. They tried to log-in multiple times it still does not work.
So one them deleted the application and reinstalled it, but still failed to login. The other one deleted the authentication information and re-register the authenticaion, but he failed as well.
What might be the causes for this issue? and how can I solve this issue?
Moreover, in the worst case of scenario, I would like to deactivate the Two Factor Authentication for all the members in the company. How can I deactivate the Two Factor Authentication?
It would be really helpful if anyone can provide me some ideas for it.
