MFA - Set up "Microsoft Authenticator App"

MFA (Multi Factor Authentication) is a more secure way to make login to services using two or more factors, meaning a password alone is not enough for a login, seeing as that easily falls into the wrong hands. By proving you also have access to the phone connected to the user, you have verified your login with high level security and with two different factors. On your phone it's easiest to set it upp with the Microsoft Authenticator App.
