App registrations allows users to register custom-developed applications for use within the directory.


Third party integrated applications connection to services should be disabled, unless there is a very clear value and robust security controls are in place. While there are legitimate uses, attackers can grant access from breached accounts to third party applications to exfiltrate data from your tenancy without having to maintain the breached account.


Implementation of this change will impact both end users and administrators. End users will not be able to integrate third-party applications that they may wish to use. Administrators are likely to receive requests from end users to grant them permission to necessary third-party applications.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


To prohibit third party integrated applications:

Navigate to Microsoft Entra admin center https://entra.microsoft.com/.

Click to expand Azure Active Directory > Users select Users settings.

Select App registrations setting highlighted to No.

Click Save.

Default Value:

Yes (Users can register applications.)
