Managing user permissions for application registrations is an important aspect of Microsoft 365 Identity and Services (exam MS-100). It involves controlling the access of individual users or groups to applications registered within an organization’s Microsoft 365 environment, thereby ensuring data security, regulatory compliance, and efficient operations.
In Azure Active Directory (Azure AD), user permissions for application registrations are managed by assigning roles. The four primary roles in Azure AD are Owner, Contributor, Reader, and Guest Inviter.
- Owner has full access to all resources, including the right to delegate permissions to others.
- Contributor can manage resources, but can’t delegate permissions.
- Reader can only view existing resources.
- Guest Inviter can manage invitations but cannot assign roles in access reviews.
In the context of application registrations, these roles can manage different aspects such as the setup and management of application properties, authentication settings, permissions to other applications, and more.
An Example of Assigning User Permissions
Let’s work through an example where a user is given permission to register an application in Azure AD.
Here are the steps:
- Sign in to the Azure portal as a Global Administrator, Security Administrator, or Application Administrator.
- Select Azure Active Directory, and then select User settings.
- Under App registrations, select Yes for Users can register applications, and then select Save.
Following these steps will allow the selected user to register an application in Azure Active Directory.
Customizing User Permissions
To further customize user permissions, you may decide you want to give a User or Group the ability to manage only a specific app registration. In such a scenario, you would use RBAC (Role Based Access Control) features in Azure AD.
For example, if you want to assign a User the Reader role for a specific application, follow these steps:
- Sign in to the Azure portal.
- Navigate to the Azure AD application registration for which you want to assign the user a role (Azure Active Directory > App registrations > Select the application).
- Select Role assignments > Add.
- From the ‘Add a role assignment’ pane that appears, select Reader from the Role dropdown.
- Find the user you wish to assign the role to by typing their name into the ‘Select’ field, then selecting their name from the dropdown menu.
- Select Save.
The selected user is now able to view the specifics of the chosen application’s registration, but cannot make any changes or delegate permissions.
Conclusion
In conclusion, managing user permissions for application registrations within Azure AD involves understanding your users’ roles and responsibilities within the organization, and then aligning these with the appropriate levels of access within the Azure AD environment. Regularly reviewing and updating these permissions will help to ensure the right balance between user flexibility and organizational security.

True or False: Global administrator or a Privileged Role Administrator can manage user permissions for any application in Azure AD.
- True
- False
Answer: True

Single Select: In Azure AD, if you are assigning application permissions, what type is it?
- a) Delegated
- b) Direct
- c) Application
- d) Admin
Answer: c) Application
Explanation: Application permissions are used by apps that run without a signed-in user present.
Only Global administrators can grant permissions to an application for sensitive Directory.Read.All and Directory.ReadWrite.All permissions. True or False?
- True
- False
Answer: True
Explanation: These permissions allow an application to read or write data of other users in the directory and only Global administrators can grant these permissions.
Which role can assign a user the ability to register an application in Azure AD? (Single select)

Answer: d) Cloud Application Administrator
Explanation: A Cloud Application Administrator can register an application in addition to managing services and identities.
True or False: API permissions include both Delegated and Application permissions.
- True
- False
Answer: True
Explanation: API permissions declare the access level that an application needs on a resource.
Who can provide consent for application’s permissions requests in Azure AD? (Multiple select)

- b) Admin
- c) Global admin
- d) Application owner
Answer: b) Admin, c) Global admin
Explanation: Only administrators or global administrators can provide consent to the application’s permissions requests.
True or False: Delegated permissions are used by apps that have a signed-in user present.
- True
