Microsoft has unveiled plans to eliminate traditional passwords for over 1 billion users across its platforms, including Outlook, Xbox, and Microsoft 365, as part of a comprehensive shift to passwordless authentication. The initiative builds on the company’s 2021 introduction of passwordless options and comes amid reports of a 200 percent surge in cyberattacks targeting login credentials.
The technology giant is moving to a passkey-first authentication model that will serve as the default sign-in method. Passkeys, which are based on FIDO Alliance standards, use cryptographic techniques and work with biometric verification methods such as facial recognition through Windows Hello and fingerprint scanning. Early testing has shown that passkey-based logins are up to three times faster than traditional password authentication.
The updated sign-in and sign-up process will feature Microsoft’s Fluent 2 design language, automatically adapting to users’ light or dark mode preferences. New account creation will begin with email-based one-time codes, followed by passkey setup as the primary authentication method. The redesign matches Microsoft’s broader effort to modernize its user interfaces across all platforms.
For existing users who have completed passkey setup, biometric authentication options will become the primary method for identity verification. The integration works with the Microsoft Authenticator app and platform-native biometric capabilities to streamline the user experience while maintaining robust security measures.
The new authentication system addresses critical cybersecurity vulnerabilities associated with traditional passwords, particularly in light of emerging threats like the Evilginx MFA bypass tool and AI-powered attack methods. Biometric authentication and cryptographic passkeys present significantly higher barriers to compromise compared to conventional password systems.
The simplified registration process requires users to enter an email address, verify it with a one-time code, and set up their passkey. The streamlined approach eliminates the complexity of traditional password-based registration methods and follows security best practices recommended by the FIDO Alliance.
Microsoft’s implementation timeline indicates that the new sign-in and sign-up flow will be deployed by the end of April 2025. Additionally, Microsoft Entra admin center, Azure portal, and Intune admin center will implement mandatory multifactor authentication (MFA) beginning in the second half of 2024, with a gradual worldwide rollout across all tenants.
The transition reflects broader industry movements toward passwordless authentication systems, as major technology companies including Google and Apple have also begun implementing passkey support. The shift is expected to influence enterprise adoption rates, with the FIDO Alliance reporting significant momentum in enterprise passkey implementation despite initial deployment challenges.
