MFA is an essential method of verifying a user’s identity by requiring multiple forms of verification during login. Generally, this is a combination of something you know (password), something you have (e.g., security token), or something you are (biometrics).
MFA for Microsoft Teams
With the number of digital threats rising each day, it is crucial to implement MFA for Microsoft Teams users. MFA in Microsoft Teams provides an extra layer of protection for your organizational data.
When configuring MFA for Microsoft Teams:
- Navigate to the Azure Active Directory portal and locate the “Security” tab.
- Click on “MFA” for the settings related to Multi-Factor Authentication.
- Here, you can turn on MFA for all users or only chosen ones by assigning MFA to a group.
Note: In scenarios where MFA might affect user experience, such as during presentations, exceptions can be configured.
Conditional Access Policies
Conditional Access is another essential tool for securing digital assets within a company. These policies can protect company resources by defining specific conditions for access. For example, access can be restricted based on the user’s location, their sign-in risk level, or the device they’re using.
Planning for Conditional Access in Microsoft Teams
When planning for Conditional Access in Microsoft Teams, it is crucial to consider factors such as user experience, security level, decision flow, and budget constraints.
Below are the steps to create Conditional Access policies for Microsoft Teams:
- Navigate to the Azure Portal and select Azure Active Directory.
- Go to Security > Conditional Access.
- Click on “+ New policy”.
- Here, you can set the specific conditions, as per the company’s requirements. These conditions could include user or group names, applications, or risk levels.
- Assign controls such as MFA and session controls.
Example: You could generate a policy wherein any access attempt from an unfamiliar location will trigger MFA.
Integrating MFA and Conditional Access
When correctly employed, MFA and Conditional Access policies can work together to form a robust, all-encompassing security system. By integrating both, administrators will provide enhanced levels of security, not just from external threats but also from potential internal risks.
Here’s an example: Consider a scenario where you have a policy set to assign MFA for all external administrative access. With Conditional Access, you can provide specifications such that if MFA is not performed or not successful, the user would be blocked from access.
By understanding and implementing these powerful measures properly, IT administrators can effectively secure the organizational information encapsulated in Microsoft Teams. As part of the MS-700 certification curriculum, mastering MFA and Conditional Access configurations is an important step toward successfully managing Microsoft Teams.
Practice Test
True/False: Multi-Factor Authentication (MFA) is not a recommended aspect of securing Microsoft Teams.
- True
- False
Answer: False
Explanation: MFA is a critical aspect of securing Microsoft Teams. It adds an extra layer of security by requiring users to verify their identity with at least two forms of identification.

- B. User risk
- C. Device platform
- D. User’s favorite color
Answer: A, B, C
Explanation: By configuring conditional access policies, you can set rules based on the user’s location, user risk, and device platform. User’s favorite color, however, is not a determinant.
True/False: The plan for conditional access and MFA for Microsoft Teams might be same for all organizations.
- True
- False
Answer: False
Explanation: Every organization’s requirements differ, and as a result, the plan for conditional access and MFA should be tailored to meet those unique needs.
Single Select: Which of the following is not a condition you can use in Conditional Access Policy in Microsoft Teams?
- A. User risk
- B. Sign-in risk
- C. Device platform
- D. Employee Rank
Answer: D. Employee Rank
Explanation: Employee rank is not a condition you can explicitly specify as part of the conditional access policy in Microsoft Teams.
True/False: Conditional Access policies are only applied to users within your organization.
- True
- False
Answer: True
Explanation: Conditional Access policies apply only to users in your organization, providing a layer of security for organizational access and data.
Multiple Select: Conditional Access in Microsoft Teams can be based on which of the following factors?
- A. User attributes
- B. Session
- C. Access controls
- D. Current weather conditions
Answer: A, B, C
Explanation: Conditional access in Teams is based on user attributes, session specifics, and defined access controls, not on irrelevant factors such as the weather.
Single Select: Which Azure feature provides added security for Microsoft Teams by requiring users to present two or more separate forms of identification?
- A. Azure Sentinel
- B. Azure Identity Protection
- C. Azure Active Directory
- D. Azure Multi-Factor Authentication
Answer: D. Azure Multi-Factor Authentication
Explanation: Azure Multi-Factor Authentication (MFA) is the feature that implements the need for users to present two or more separate forms of identification for added security.
True/False: If your team uses multiple Microsoft 365 services, you need to create a separate conditional access policy for each service.
- True
- False
Answer: False
Explanation: Conditional access policies span across all Microsoft 365 services, so separate policies for each service are not needed.
Multiple select: What are the two major categories of conditions available under Conditional Access in Microsoft Teams?
- A. Assignments
- B. Access controls
- C. Session
- D. Applications
Answer: A. Assignments and B. Access controls
Explanation: In Azure AD Conditional Access, the two major categories are “Assignments,” which determine the “who,” “where,” and “what,” and “Access controls,” which determine the “how.”
True/False: MFA is optional when it comes to securing Microsoft Teams?
- True
- False
Answer: False
”
Explanation: While MFA is not necessarily “mandatory,” it is highly recommended as a best practice for security in Microsoft Teams.
Single Select: Which type of policy allows rules to be set for a user or group, a cloud app, or a condition within Microsoft Teams?
- A. Sharing policy
- B. Conditional access policy
- C. Compliance policy
- D. Privacy policy
Answer: B. Conditional access policy
Explanation: A conditional access policy in Microsoft Teams allows rules to be set for a user or group, a cloud app, or a condition, enabling more effective security management.
Interview Questions
What is conditional access in terms of Microsoft Teams?
Conditional access is a capability of Azure Active Directory that enables you to enforce controls on the access to applications in your environment based on specific conditions from a central location.
What does MFA stand for and how is it used in Microsoft Teams?
MFA stands for Multi-Factor Authentication. It adds an additional layer of security to the user sign-in process. It forces users to verify their identity using at least two different forms of authentication before granting access to the application.
