Microsoft Edge lets users log into password protected sites without showing the password

Microsoft Edge has introduced a significant security enhancement that allows users to log into password-protected websites without directly revealing their passwords on screen during the autofill process. This feature adds an extra layer of privacy and security, ensuring that even if someone gains temporary access to an unlocked computer, their ability to access sensitive online accounts is significantly hindered.

This advanced capability is integrated into Microsoft Edge’s robust password management system, which already provides secure storage and autofill for credentials. By requiring an additional authentication step before populating password fields, Edge offers a more secure browsing experience, protecting users from potential unauthorized access and enhancing overall digital safety.

Enhanced Security Through Device Authentication

Microsoft Edge has implemented a new security measure that requires users to authenticate using their device credentials before it will autofill saved passwords for a website. This means that even if a password is saved within the browser, it cannot be automatically entered into a login form without an additional verification step.

This process typically involves re-entering your device’s password, PIN, or using biometric authentication such as a fingerprint or facial scan, depending on your system’s setup. This added authentication acts as a crucial barrier, preventing unauthorized individuals who might gain access to an unlocked computer from easily logging into your online accounts.

The implementation of device authentication before password autofill significantly bolsters privacy. It ensures that no one who doesn’t know your device’s password can leverage your saved credentials, thereby preventing both accidental and intentional misuse of your online identities. This feature is particularly valuable for users who frequently leave their computers unattended, even for short periods.

How the Passwordless Autofill Feature Works

When you visit a website for which Microsoft Edge has saved your login credentials, the browser will now prompt you for device authentication before it auto-fills the password field. This is a departure from the previous behavior where saved passwords would be entered directly upon visiting the login page.

The user experience involves visiting a password-protected site, and upon the appearance of the login fields, Edge will present a prompt. This prompt requires you to verify your identity through your device’s security measures, such as entering your Windows login password or using Windows Hello (biometrics like fingerprint or facial recognition). Only after successful authentication will Edge proceed to fill in the username and password fields.

This layered security approach ensures that even if someone has access to your unlocked device, they cannot simply use the browser’s autofill functionality to access your accounts. They would first need to bypass your device’s primary security, making it a more robust defense against unauthorized access.

Enabling and Configuring the Feature

To take advantage of this enhanced security, users need to ensure the feature is enabled within Microsoft Edge’s settings. The process is straightforward and involves navigating to the password manager section of the browser’s preferences.

Users can find this setting by going to `edge://settings/autofill/passwords` and selecting “Microsoft Password Manager,” followed by “More settings.” Within this menu, there is a toggle for “Autofill passwords and passkeys,” and a sub-option to “Prompt for device sign-in before viewing or filling website password”.

This option can be configured to “Always ask for permission” or to “Ask permission once per browsing session,” providing a balance between security and convenience depending on user preference. Enabling this setting ensures that each time a password is to be autofilled, your device’s credentials will be required.

Understanding the Security Implications and Limitations

While requiring device authentication before autofill adds a significant layer of privacy, it’s important to understand its limitations. This feature is designed to protect against scenarios where someone gains physical access to your unlocked computer.

It is not a foolproof solution against sophisticated cyber threats. Malware or keyloggers installed on your device could still potentially capture your passwords, and determined attackers with administrative access might find ways to disable the setting or bypass it. Microsoft recommends that for the highest level of security on a shared device, each user should have their own distinct user account on the computer.

The browser encrypts stored passwords using AES and saves the encryption key within the operating system’s secure storage area. This local data encryption protects sensitive information like passwords and credit card numbers when they are saved. However, if malware compromises the operating system itself, it could potentially access decrypted data.

Microsoft Edge’s Broader Password Management Ecosystem

The enhanced authentication for autofill is part of Microsoft Edge’s comprehensive approach to password management. The browser offers a suite of features designed to make handling online credentials more secure and convenient.

These features include a password generator that creates strong, unique passwords for new accounts, which are then automatically saved and synced across devices. Microsoft Edge also includes a Password Monitor that alerts users if any of their saved passwords have been compromised in data breaches, prompting them to update their credentials promptly.

Furthermore, the browser provides a password health check, which reviews stored passwords and flags any that are weak, reused, or potentially compromised, guiding users toward better password hygiene. This integrated ecosystem aims to simplify credential management while significantly improving online security for its users.

Passwordless Authentication: The Future of Access

Beyond the autofill security enhancement, Microsoft is heavily invested in promoting true passwordless authentication. This involves moving away from traditional passwords altogether, utilizing more secure methods for logging into accounts and services.

Microsoft Edge supports web authentication standards, allowing users to sign in using biometrics like facial recognition or fingerprint scans, or through PINs and FIDO2 security keys. This aligns with Microsoft’s broader strategy to offer passwordless sign-in options for Microsoft accounts, making access to services like Microsoft 365, Teams, and Edge itself more secure and convenient.

The move towards passwordless authentication aims to drastically reduce the risk of account takeovers, as these methods are inherently more resistant to phishing and credential stuffing attacks than traditional passwords. By leveraging technologies like Windows Hello, Edge facilitates a more seamless and secure entry into the digital world.

Secure Password Deployment for Organizations

For enterprise environments, Microsoft Edge offers a feature called “Secure Password Deployment”. This capability allows administrators to deploy encrypted shared passwords to specific users within an organization. This addresses the common insecure practice of sharing passwords via email or sticky notes.

With secure password deployment, users receive encrypted credentials that can be used for seamless logins without ever seeing the actual password. This feature is managed through the Microsoft 365 admin center and integrated into the Edge management service, providing a streamlined way to manage and revoke access to shared accounts.

This enterprise-focused solution enhances an organization’s security posture by minimizing the risk of unauthorized access through shared credentials. It ensures that sensitive login information is handled securely and remains protected, even when shared among team members.

Deprecation of Custom Primary Passwords

In a move towards simplifying security and relying on system-level authentication, Microsoft has deprecated the custom primary password feature in Microsoft Edge. Previously, users could set a custom password to protect their saved data within Edge.

Starting with Edge version 146, users can no longer create new custom primary passwords. Existing users were warned that this feature would be unavailable from June 4, 2026, after which they would be automatically migrated to device authentication. This strategic shift emphasizes the use of device credentials, such as Windows Hello, as a more secure and convenient method for authenticating access to saved passwords.

This deprecation aligns with Microsoft’s broader security philosophy, which prioritizes leveraging the inherent security of the operating system and user devices over a separate, potentially weaker, custom password. The goal is to streamline the user experience while enhancing overall security by relying on robust, system-wide authentication mechanisms.

Autofill Management and User Control

Microsoft Edge provides users with granular control over its autofill capabilities, including password autofill. Users can choose to enable or disable the feature entirely, or manage specific aspects of it within the browser’s settings.

Within the “Passwords and autofill” section of Edge settings, users can manage their saved passwords, including enabling or disabling the prompt to save new passwords. This allows individuals to tailor the autofill experience to their comfort level with convenience versus security.

For those concerned about privacy on shared computers, disabling password autofill is a recommended step. This ensures that sensitive login information is not automatically populated, preventing unauthorized users from accessing accounts, even if the browser is left open.

Integration with Microsoft Account and Cross-Device Sync

The password management features in Microsoft Edge are tightly integrated with a user’s Microsoft account. When signed into Edge with a Microsoft account, saved passwords and other credentials can sync across all devices where the user is logged in with the same account.

This seamless cross-device synchronization ensures that users have access to their login information wherever they browse using Edge. This convenience is a key benefit for users who utilize multiple devices for their online activities.

However, this integration also means that the security of your synced passwords relies on the security of your Microsoft account. Strong Microsoft account security, including robust passwordless methods or a strong account password, is therefore paramount.

Security Measures for Stored Passwords

Microsoft Edge employs robust encryption methods to protect users’ saved passwords. Passwords are encrypted on disk using the AES cipher, with the encryption key itself being protected and stored within the operating system’s secure storage area, such as DPAPI on Windows or Keychain on macOS.

This local data encryption ensures that even if someone gains physical access to the computer and its files, they cannot easily read the plaintext passwords if the user is not logged into the operating system. The system is designed to prevent unauthorized access to credentials when the user is logged out.

While these measures provide strong protection against many local threats, it’s important to note that sophisticated malware or attackers with administrative privileges might still find ways to access or decrypt this data under certain circumstances. Therefore, maintaining overall system security through up-to-date antivirus software and vigilant browsing habits remains essential.

Password Health and Monitoring Features

Microsoft Edge’s password manager includes features aimed at proactively improving users’ password security. The “Password health check” analyzes stored passwords, identifying any that are weak, reused across multiple sites, or have been exposed in data breaches.

The “Password Monitor” actively scans the dark web and other sources for compromised credentials. If any of your saved passwords are found to be exposed, Edge will alert you, prompting you to change them immediately. This proactive monitoring is crucial for preventing account takeovers, as compromised credentials are a common entry point for cyberattacks.

These built-in tools empower users to take informed actions to strengthen their online security. By providing clear insights into password vulnerabilities, Edge helps users maintain better password management practices and protect their accounts from potential breaches.
