Microsoft introduces Passkeys as standard in Entra ID

Microsoft introduced the use of Passkeys as standard authentication in Entra ID in September 2026. This move aims to enhance the security of user accounts and minimize the risks of cyberattacks. However, the decision to make Passkeys the norm also brings significant changes to tenant configurations that may occur without the explicit consent of administrators.

Andrea Sivieri, Chief Product and Technology Officer at Microsoft 365 management provider CoreView, expressed concerns about the implications of this change. He warns that the enforced method shift could catch IT departments off guard. This could represent a critical window of time for both attackers and help desks, during which additional challenges may arise.

Changes in Tenant Configuration

The transition to Passkeys means that existing authentication methods may no longer function or may need to be adjusted. Administrators will need to prepare for a new configuration that may require additional training and adjustments. These changes could lead to confusion and uncertainty within IT departments, as administrators must adapt to the new standards.

The introduction of Passkeys could also impact user-friendliness. While Passkeys are considered more secure, the transition may present a learning curve for some users. The need to adapt to new authentication methods could lead to initial difficulties, especially for less tech-savvy employees.

Security Aspects and Challenges

The decision to implement Passkeys as standard is part of Microsoft's comprehensive strategy to enhance cybersecurity. Passkeys offer stronger security compared to traditional passwords, as they are less susceptible to phishing attacks. Nevertheless, the transition also presents challenges, particularly regarding user training and the adaptation of IT infrastructure.

IT departments must prepare for the possibility that the transition to Passkeys may require additional resources. This could include the need to review and potentially update existing systems to support the new authentication method. The challenge lies in increasing security without compromising user-friendliness.

The introduction of Passkeys in Entra ID is a significant step in the evolution of Microsoft's security strategies. The impact of this change will be closely monitored in the coming months as companies attempt to adapt to the new requirements. The reactions of administrators and users will be crucial to how successful this transition ultimately is.

Microsoft has completed the transition to Passkeys as standard authentication in Entra ID in September 2026, which brings significant changes to tenant configurations.
