# Enterprise Application

### 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](/quickstart-guide/ios-mam-steps-to-activate-sca-in-your-azure-tenant/step-1-register-enterprise-app.md#step1-registerenterpriseapp-enterpriseappregistrationfromthescahomepage).
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
```

2. Open the URL in your browser.
3. Sign in with an account that has the **Global Administrator** role.
4. 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](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**
{% endhint %}

{% hint style="danger" %}
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

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.secure-contacts.com/documentation/authentication/enterprise-application.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
