Hello Satheesh K B,Users need to have an MFA authentication app (for example, Google Authenticator, Auth0 Guardian, etc.) permanently install on one of their mobile devices for as long as they need to continue on accessing a Microsoft Advertising application that requires MFA as part of the authentication process. If you have deleted the app, the way to resolve this is to request for Product Support to reset MFA for the affected users. Contact Product Support with the email address for the affected user.
