Listen to this Post

With the rollout of Entra External Authentication Methods in System Preferred MFA starting in March, organizations are set to enhance their security frameworks. This update prioritizes external authentication methods over Microsoft Authenticator, while maintaining the precedence of TAP (Temporary Access Pass) and security keys.

Key Features:

  • External Authentication Methods: Preferred over Microsoft Authenticator.
  • TAP and Security Keys: Continue to be the top priority for authentication.

Practical Implementation:

To configure and verify the new authentication methods, you can use the following PowerShell commands:


<h1>Check current MFA settings</h1>

Get-MsolUser -UserPrincipalName [email protected] | Select-Object -ExpandProperty StrongAuthenticationMethods

<h1>Enable External Authentication Method</h1>

Set-MsolUser -UserPrincipalName [email protected] -StrongAuthenticationMethods @{MethodType="External"}

For Linux users managing systems integrated with Entra, you can use the following commands to ensure your system is ready for the update:


<h1>Check for necessary updates</h1>

sudo apt-get update
sudo apt-get upgrade -y

<h1>Verify network configurations</h1>

ip a
ping entra.microsoft.com

What Undercode Say:

The of Entra External Authentication Methods in System Preferred MFA marks a significant step forward in cybersecurity. By prioritizing external methods, organizations can leverage a more robust and flexible authentication framework. This update not only enhances security but also simplifies the user experience by reducing dependency on a single authentication method.

For IT administrators, the transition to this new system involves a series of configurations and verifications. Utilizing PowerShell commands, as demonstrated, ensures a smooth implementation process. Linux users, on the other hand, should ensure their systems are up-to-date and properly configured to support these new authentication methods.

In the broader context of cybersecurity, this update underscores the importance of multi-factor authentication (MFA) in protecting sensitive data. As cyber threats continue to evolve, adopting advanced authentication methods becomes crucial. The integration of external authentication methods, TAP, and security keys provides a comprehensive defense mechanism against unauthorized access.
