     In today's world of cloud technology, security is a an ever growing requirement. In Microsoft Azure, you can enhance the security for your cloud platform by enabling MFA, often referred to as 2-step verification. MFA enables a secondary method of authentication for your Azure tenant, in the form a text message, phone call or mobile app code.      Many platforms on the internet use this technology, including Facebook, Google and Apple. It only makes sense to enable this for your own user base, for the purpose of enhanced network security and the protection of your data and applications in the cloud and if you wish, on-premises networks too! Even if attackers manage to guess the password for one of your users, its completely useless as without the secondary verification method, they will not get in.
