Connecting to MFA enabled Microsoft Dynamics 365 using XrmToolBox

Multi-factor authentication (MFA) is becoming a necessity for organizations looking to tighten their security. As a result, developers can face difficulty connecting their applications to Dynamics 365.

In this article, we will explore how to connect XrmToolBox to MFA enabled Dynamics 365.

Note: Per the official XrmToolBox website, the only way to connect to MFA secured organizations is to use a connection string. But in order to do that, we will have to create an Azure AD app and set some parameters. Not to worry, we will guide you through every step of the way.
