Assistance Required for Accessing Microsoft Graph API Delegated Permissions Without User Interaction

Question

Hi Guys,

Previously, we utilized a console application to access users' mail content within our application (registered as a confidential client in Azure Active Directory). However, we now require the ability to access Microsoft Graph API's delegated permissions to read a user's mail using only their email and password.

Our goal is to achieve this using a console application while meeting the following conditions:

1.Multi-Factor Authentication (MFA) is enabled.

2.No user interaction is required.

3.Admin consent is not necessary.

4.Hosted application should remain as Confidential client application

Could you kindly suggest an authentication method that would allow us to meet these requirements?

Thank you for your assistance.

Hi @Naresh kumar

If you want to use a console application to access the Graph API, there are two ways to authenticate, but neither of them will meet your needs, so let me explain in detail below:

1.Delegated (user) authentication: This authentication method uses delegated permissions, but requires the user to log in interactively for authorization.

2.App-only authentication: This authentication mode uses the application permission and does not require the user to log in. However, the application permission can only be granted by the administrator.

For detailed authentication methods and code for console applications, see this documentation.

Hope this helps.
