Microsoft will enable passkeys as the default authentication method in Entra ID starting September 2026. This transition affects the central identity management system for enterprise environments.
Microsoft has announced that it will introduce passkeys as the default authentication method in the enterprise identity service Entra ID. The rollout begins in September 2026 and affects all organizations using Entra ID.
For CISOs, this represents a fundamental shift in the authentication landscape: passkeys replace password-based procedures with cryptographic keys stored on devices and unlocked through biometric or PIN authentication. This significantly reduces the attack surface for phishing and credential stuffing, since passwords cannot be transmitted or compromised.
The transition requires timely planning: organizations should prepare their infrastructure, processes, and training measures for this authentication method. Compatibility with existing systems and applications must be verified before the deadline to prevent downtime.
