Multi-factor authentication (MFA) has become essential for enterprise data security to prevent unauthorized access to critical resources. One function in the SC-300 Microsoft Identity and Access Administrator exam is implementing and managing MFA registration policy. This involves configuring the MFA settings under the Azure Active Directory (Azure AD) in the Microsoft 365 admin center.
MFA Registration Policy:
MFA registration can be initialized from the Azure AD portal by following the steps below:
- Navigate to the Azure portal.
- Select Azure Active Directory.
- From the Azure AD menu, choose Security.
- Select MFA.
- On the MFA page, select the ‘Getting Started’ button present on the MFA registration policy page.
You will then create an MFA registration policy where you can choose the application, the user action, the conditions during which the policy is applied, and the MFA control.
For example:
'app': 'All',
'userAction': 'register',
'conditions': {
'location': {
'in': ['All locations']
},
'platform': {
'in': ['All platforms']
},
'clientApp': {
'in': ['Browser']
},
},
'grantControls': {
'MFA': 'required'
}
Your new policy may take up to 24 hours to be effective across your tenancy.
Managing MFA Policy:
The management of MFA policy involves modifying, monitoring, and reviewing MFA settings.
To modify the user MFA settings:
- In the admin center, go to the active users page, and select a user.
- In the user pane, under the user sign-in section, select the Manage multi-factor authentication link.
- The multi-factor authentication page gets displayed with all the users list. You can perform bulk updates by selecting multiple users, or go to the individual user to update MFA settings.
Monitoring the MFA policy is an equally important task:
To monitor MFA status:
- On your Azure portal, go to the Azure Active Directory.
- On the main panel, select Users.
- Next, click on Multi-Factor Authentication. This lists all the users and their MFA status.
These are the basic steps used to implement and manage the MFA registration policy as taught in the “SC-300: Microsoft Identity and Access Administrator” certification. The actual tasks may vary based on your organizational needs and requirements. Remember that any changes in your policies require due diligence and testing before they are applied to the production environment.

Answer: False
Explanation: Protecting administrator accounts with MFA is a recognized security best practice that helps protect against unauthorized access.
To implement an MFA registration policy, you need to have the role of:
- A) User
- B) Guest
- C) Administrator
- D) Developer
Answer: C) Administrator
Explanation: In Microsoft, the Administrator or someone with equivalent permissions can implement and manage MFA registration policy.
True or False: An MFA registration policy can be bypassed if the user forgets their password.
- True
- False
Answer: False
Explanation: MFA is designed to protect against unauthorized access, including situations where a password is forgotten. It requires more than one form of authentication to grant access.
Which of the following is NOT a consideration when implementing an MFA registration policy?
- A) The number of users within the organization
- B) The cost of implementing the policy
- C) The color of the company’s logo
- D) The type of data and systems being protected
Answer: C) The color of the company’s logo
Explanation: The color of the company’s logo is irrelevant to implementing an MFA registration policy. The other options are valid considerations.
Effective MFA registration policies should:
- A) Allow users to choose their method of authentication
- B) Require regular updates to authentication methods
- C) Protect against a wide variety of security threats
- D) All of the above
Answer: D) All of the above
Explanation: All of these aspects contribute to the effectiveness of an MFA registration policy.
True or False: MFA registration policy can only be applied at an organization level.
- True
- False
Answer: False
Explanation: MFA registration policy can be applied at different levels – user level, group level, or organization level, based on the security requirements and policy management.
Which two Microsoft services support MFA?
- A) Azure AD
