How to Enable Multi-Factor Authentication for SQL Server

Implementing Multi-Factor Authentication (MFA)

Write a SQL query to configure multi-factor authentication (MFA) for database access.

Solution:

-- Configure MFA for a SQL login using Azure Active Directory.
CREATE LOGIN [[email protected]] FROM EXTERNAL PROVIDER;

Explanation:

• Purpose of the Query :
• The goal is to demonstrate how to configure MFA for secure database access.
• Key Components :
• CREATE LOGIN: Creates a login using Azure Active Directory.
• EXTERNAL PROVIDER: Integrates with Azure AD for MFA.
• [email protected]: Specifies the user's email address.
• Why Use MFA? :
• MFA adds an extra layer of security by requiring multiple forms of verification.
• It reduces the risk of unauthorized access due to stolen credentials.
• Real-World Application :
• In cloud environments, MFA protects sensitive data from cyber threats.

Additional Notes:

• MFA is supported in Azure SQL Database and other cloud platforms.
• Integrate with identity providers like Azure AD or Okta.
• Important Considerations:
• Ensure that MFA is enabled for all critical accounts.

For more Practice: Solve these Related Problems:

• Write a SQL query to configure MFA for a user accessing the database via Azure Active Directory.
• Write a SQL query to integrate MFA with an identity provider like Okta for secure database access.
• Write a SQL query to enforce MFA for all administrative accounts in the database.
• Write a SQL query to audit users who have not enabled MFA for their database accounts.
