Migrating your MFA (Multi-Factor Authentication) and SSPR (Self-Service Password Reset) policy settings to the Authentication methods policy in Microsoft Entra ID is a crucial step to streamline and enhance your security management. Here's a detailed guide on how to do it and what you need to ensure a smooth transition:

Steps to Migrate MFA and SSPR Policy Settings

1. Audit Current Policies:
• MFA: Review your existing MFA settings by navigating to the Azure Microsoft Entra Admin Portal, selecting Azure Active Directory, and then Security > Multifactor authentication[1].
• SSPR: Similarly, audit your SSPR settings by going to Identity > Users > Password reset > Authentication methods[1].
2. Automated Migration:
• Use the authentication methods migration guide in the Microsoft Entra admin center. This guide provides a wizard to help audit your current policy settings for MFA and SSPR and consolidates those settings into the Authentication methods policy[1].
• Access the migration guide by browsing to Protection > Authentication methods > Policies in the Microsoft Entra admin center[1].
3. Manual Migration:
• If you prefer a manual approach, start by documenting your existing policy settings for each authentication method available to users[1].
• Configure the Authentication methods policy to match your current settings, ensuring that users can continue to sign in and reset their passwords using the same methods[1].
4. Testing and Validation:
• Thoroughly test the new Authentication methods policy to ensure it works as expected without disrupting user access[2].
• Enable modern, secure methods like passkeys, Temporary Access Pass, and Microsoft Authenticator to improve security[1].
5. Final Migration:
• Once satisfied with the configuration, select Migrate in the wizard and confirm the migration[1].
• The legacy MFA and SSPR policies will become grayed out and no longer apply[1].

Impact and Best Practices

• Unified Management: The new Authentication methods policy allows you to manage MFA and SSPR settings from a single portal, simplifying administration[2].
• Improved Security: By enabling modern authentication methods, you enhance your organization's security posture[1].
• Reversibility: The migration process is fully reversible, allowing you to revert to legacy policies if needed[1].

Ensuring a Smooth Transition

• Plan Ahead: Start the migration process well before the September 30, 2025 deadline to avoid a rushed transition[2].
• Communicate with Users: Inform your users about the upcoming changes and provide training if necessary to ensure they are comfortable with the new authentication methods[2].
• Monitor and Adjust: Continuously monitor the new policy's performance and make adjustments as needed to address any issues that arise[2].
