The organization needs to transition to a centralized management system for multifactor authentication (MFA), passwordless sign-in, and security keys without disrupting user access.
Before you start

Before initiating the migration, thoroughly review your organization's current legacy MFA and SSPR (Self-Service Password Reset) policies to ensure all existing user authentication methods are accounted for.

Solution 1Recommended

Plan and Execute the Entra Authentication Methods Migration

Follow a phased approach to centralize authentication management, enabling features like passwordless sign-in and security keys without disrupting users.

Migrating to the new Authentication Methods policy provides a unified, centralized administrative interface to manage how users sign in. It replaces the fragmented legacy MFA and SSPR portals, offering granular control over modern authentication protocols.

1
Review Current Policies

Audit your existing legacy multifactor authentication (MFA) and self-service password reset (SSPR) policies to understand current user capabilities and group assignments.

2
Enable Centralized Management

Access the Microsoft Entra admin center as an Authentication Policy Administrator, and navigate to Protection > Authentication methods > Policies to begin configuring the unified policy.

3
Configure Target Authentication Methods

Set up the desired authentication methods for your organization, such as Microsoft Authenticator, FIDO2 security keys, or SMS/Voice, and assign them to specific user groups.

4
Test with a Pilot Group

Roll out the new Authentication Methods policy to a small, controlled pilot group of users. Monitor their sign-in logs to identify and resolve any disruptions before a broader deployment.

5
Complete the Migration

Once testing is successful and all legacy policies are translated, change the migration state to 'Migration Complete' in the admin center to fully transition away from legacy systems.

Frequently Asked Questions

What are the benefits of migrating to the new Entra Authentication Methods policy?

Migrating centralizes the management of all authentication methods, including MFA, passwordless sign-in, and FIDO2 security keys, into a single, unified administrative portal rather than managing them across fragmented legacy portals.

Will migrating to the new policy disrupt user sign-ins?

It shouldn't disrupt sign-ins if planned correctly. By testing the new policy settings with a pilot group of users before completing a tenant-wide rollout, you can identify and resolve any configuration issues without causing broad access disruptions.

Can I still use legacy MFA and SSPR policies after the migration is finished?

Once you set the migration state to 'Migration Complete' in the admin portal, legacy MFA and SSPR policies are deprecated and ignored for your tenant. All authentication management will be strictly handled via the new centralized policy.

What specific authentication methods can be managed in the new Entra policy?

Administrators can manage a wide array of modern methods including Microsoft Authenticator, SMS, Voice calls, FIDO2 security keys, Certificate-based authentication, Windows Hello for Business, and Temporary Access Passes.
