Microsoft's move towards a passwordless authentication system, set to begin in August 2025, is part of a broader initiative to enhance online security by replacing traditional passwords with passkeys.

In six weeks, Microsoft will begin a significant transition by deleting passwords from its Authenticator app, urging users to migrate to passkeys.

Key deadlines for this transition include the inability to save new passwords starting in June 2025, the disabling of autofill in July 2025, and the complete removal of saved passwords by August 2025.

From June 2025, the Microsoft Authenticator app will no longer allow users to add passwords, culminating in the total removal of saved passwords by August 2025.

Passkeys, which leverage public key cryptography, provide a more secure alternative to passwords by utilizing biometric data or PINs for authentication, thereby reducing vulnerability to phishing and brute-force attacks.

Users are encouraged to utilize Microsoft Edge for secure password storage and to take advantage of the autofill feature for a smoother experience.

Both Microsoft and Google advocate for the transition to passkeys as a more secure option, given the susceptibility of traditional passwords to phishing attacks.

While users can still store passwords in Microsoft Edge, experts recommend switching to passkeys for enhanced security.

A recent CNET survey found that 49% of U.S. adults engage in risky password practices, such as reusing passwords and using personal information, which heightens the risk of identity theft and fraud.

As cybercriminals intensify password-related attacks during this transition, the urgency of switching to passkeys becomes even more critical.

The Microsoft Authenticator will continue to support passkeys, and users must keep the app enabled to ensure their passkeys remain functional.

To set up a passkey in Microsoft Authenticator, users should log into their account, select 'Set up a passkey' from the app, and follow the prompts to complete the enrollment.
