Microsoft has unveiled a comprehensive plan to eliminate passwords across its ecosystem by 2025, marking a significant evolution in the company’s years-long push toward more secure authentication methods. The initiative is part of the company’s broader Zero Trust security strategy that prioritizes robust identity verification beyond traditional passwords, building on Microsoft’s earlier successful implementations of passwordless solutions.
The company plans to completely remove traditional password management, including from its Authenticator app, by August 2025. The transition affects all Microsoft services and products, targeting legacy authentication protocols such as POP, IMAP, SMTP Basic, and MAPI, which lack support for modern security features like Multi-Factor Authentication (MFA). The move follows Microsoft’s announcement of native passkey support in the Authenticator app, scheduled for mid-January 2025.
The shift to a Zero Trust security model requires continuous verification of user identities and device compliance. Microsoft Entra ID Conditional Access policies play a central role in this transformation, enabling organizations to implement identity- and device-based access controls while eliminating legacy authentication methods. Recent data shows that passwordless authentication through Entra ID has demonstrated login speeds three times faster than traditional methods.
“Removing legacy auth isn’t a nice-to-have — it’s a prerequisite for a modern security strategy,” said Gonzalo Brown Ruiz, Senior Microsoft 365 Engineer & Cloud Security Specialist. “By combining deep visibility, staged enforcement, and a user-centric approach, organizations can securely modernize their identity perimeter.”
Organizations and users must take several key actions to prepare for this transition. These include adopting passwordless sign-in methods such as Windows Hello, FIDO2 security keys, and the Microsoft Authenticator app. Additionally, enabling Multi-Factor Authentication remains crucial and is integrated into passwordless solutions. Recent research has highlighted both the strengths and potential vulnerabilities of FIDO2 authentication and synced passkeys, emphasizing the importance of proper implementation.
The Microsoft Authenticator app is receiving updates to enhance backup and recovery capabilities, particularly for iOS devices. The app will now use iCloud Keychain instead of requiring a Microsoft personal account for credential backup. The update applies automatically to devices running iOS 16.0 or later, streamlining the user experience during device transitions. The change matches broader industry trends, as passkey adoption has surged 550 percent in 2024 across major technology platforms.
Organizations need to conduct thorough audits of their environments to identify and phase out legacy authentication protocols, replacing them with modern, secure alternatives. “Instead of using a Microsoft account for backup and recovery, Authenticator will use the iCloud keychain,” noted the Office 365 IT Pros team. “Users don’t have to do anything to benefit from the update.”
