Microsoft Is Phasing Out MFA via SMS and Phone Calls—Is Your Organization Ready?

Microsoft is currently implementing a major change in identity and security management. SMS and phone calls as methods of multi-factor authentication (MFA) will be phased out in favor of more modern and secure authentication methods, particularly Passkeys.

For many organizations, this presents a natural opportunity to enhance security, simplify the user login experience, and at the same time prepare for upcoming requirements from Microsoft.

Phasing Out MFA

What is a Passkey? 

A Passkeyis a modern way to log in without a password or SMS codes. Instead, it uses something you already use every day, such as a fingerprint, facial recognition, or the PIN on your computer or cell phone. 

For users, this means faster and easier logins. For the organization, it means significantly better protection against phishing, stolen passwords, and account takeovers. Passkeys are also the authentication method that Microsoft highlights as a central part of future identity protection. 

 

Important Dates 

September 1, 2026 

Microsoft will automatically begin prompting users who currently use SMS or phone calls for MFA to register a passkey. 

February 1, 2027 

Microsoft will completely discontinue support for SMS- and call-based MFA. Organizations that still rely on these methods will need to have transitioned to other authentication solutions by then. 

 

What does Microsoft recommend? 

Microsoft recommends that organizations: 

  • Ensures that all users have MFA enabled. 
  • We are gradually transitioning to modern authentication methods that are secure against phishing. 
  • Implement Passkeys as a long-term, future-proof authentication solution. 
  • Reduces reliance on text messages and phone calls for verification.

 

What should you be doing right now?

Even though the deadline is still some time away, we recommend starting the work now to avoid stress and unnecessary operational disruptions down the line. 

We recommend that you: 

  •  Identifying which authentication methods are currently in use. 
  • Identifies users who still use text messages or phone calls for MFA. 
  • Ensures that all users have MFA enabled. 
  • Develop a plan for transitioning to Passkeys. 
  • Notifies users well in advance of the change taking effect. 
  • Tests and verifies that the organization's various units and work processes are compatible with Passkeys. 

 

Our recommendation for users 

To ensure a seamless and robust solution, we recommend that each user register at least two Passkeys: 

  • A Passkey on your cell phone via Microsoft Authenticator. 
  • A Passkey on the work computer using Windows Hello and the personal PIN. 

This provides users with a backup solution in case their phone is lost or replaced, while also making it easy to log in regardless of whether they’re working from a phone, tablet, or computer. 

How does this affect you?

If you use text messages or phone calls for MFA

You need to plan for a transition to Passkeys or another modern authentication method by February 2027.

If you're already using Microsoft Authenticator

You are not normally directly affected by this change, but this is a good opportunity to take the next step and implement Passkeys for even better security and a better user experience.

If you don't have MFA today

Microsoft recommends enabling MFA for all users, preferably using modern methods such as passkeys from the start.

Here's how we can help you 

Implementing Passkeys isn't just about technology. It's also about planning, user support, and change management. 

We can help you: 

  • Assess the current situation and identify which users are affected. 
  • Get a handle on existing MFA methods and security settings. 
  • Develop a recommended plan for the implementation of Passkeys. 
  • Implement and configure the solution in Microsoft 365. 
  • Ensure that users receive the correct information and training. 
  • Support the organization throughout the transition. 

 

Next Step 

Microsoft's change presents an opportunity to both enhance security and simplify users' daily lives. By starting the process now, the transition can take place in a phased and controlled manner before the upcoming deadlines approach. 

We’d be happy to help you analyze your current situation and develop a plan for a safe and smooth transition.
