About Enterprise Application Registration

An Enterprise Application in Azure Active Directory (Azure AD) is an app registered in your organization’s directory.

The Secure Contacts App (SCA) needs to be registered as an Enterprise Application to:

• Authenticate users securely via Azure AD.

• Access organizational data such as contacts, groups, and directory information.

• Enable centralized management and compliance of app permissions within your tenant.

Registering SCA ensures that administrators can control access and grant only the permissions necessary for the app to operate safely in the organization.

How to Register the SCA Enterprise Application

There are two ways to register SCA as an Enterprise Application:

1. Via the SCA Homepage

1. Go to the Secure Contacts App homepage.

2. In the Admin-Consent section, enter your Azure AD tenant ID and click Add.

3. Sign in with an account that has the Global Administrator role.

4. Grant tenant-wide admin consent to complete the registration.

2. Manual Registration via URL

1. Construct the following URL, replacing {tenant-id} with your Azure AD tenant ID:

https://login.microsoftonline.com/{tenant-id}/adminconsent?client_id=20429334-d869-476e-8a65-ea300a327985

1. Open the URL in your browser.

2. Sign in with an account that has the Global Administrator role.

3. Review and grant tenant-wide admin consent.

Example: https://login.microsoftonline.com/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/adminconsent?client_id=20429334-d869-476e-8a65-ea300a327985

XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX = Replace this with your own Tenant-ID 20429334-d869-476e-8a65-ea300a327985 = Enterprise-App-ID of Secure Contacts App

The admin consent page may sometimes get stuck in a loop and not provide feedback. To verify the registration:

• Check if the Enterprise Application "Secure Contacts App" appears in your Azure AD.

• If you encounter any issues with registering SCA in Azure AD, contact our support team for assistance
