Microsoft Edge will permanently retire its Custom Primary Password feature on June 4, 2026, pushing all users who previously relied on an extra layer of password protection toward device-based authentication methods like Windows Hello and system passwords. The change, first announced quietly in Microsoft’s documentation updates, removes the optional master password that allowed Edge users to encrypt their locally stored web credentials with a secret distinct from their Windows account credentials.

The move aligns Edge’s password management more closely with the broader industry shift toward biometric and device-bound security, but it also raises concerns among privacy-conscious users and those sharing machines. Here’s everything you need to know about the transition, its security implications, and how to prepare.

A Farewell to the Custom Primary Password

Microsoft Edge’s built-in password manager has long offered the ability to save and automatically fill passwords across websites. For extra protection, users could enable a Custom Primary Password—a feature inherited from Edge’s roots in classic Microsoft Edge (non-Chromium) and carried into the Chromium-based version. Once set, this password had to be entered whenever you wanted to view saved passwords in Settings or have Edge autofill them on a page. Crucially, the Custom Primary Password was separate from your Windows account password or PIN, providing an independent security boundary.

The feature was opt-in; many users never activated it. But for those who did, it offered peace of mind: even if someone gained access to their unlocked Windows desktop, they would still need that secondary password to extract saved logins. This was particularly valuable on shared family computers or in office environments where quick desktop access might not imply authorization to view all web credentials.

Starting June 4, 2026, Edge will no longer present the option to set a Custom Primary Password. For users who currently rely on it, the setting will be silently removed, and Edge will default to requiring device-based authentication whenever a password needs to be revealed or filled. Microsoft states in its support article that the change is rolling out with a stable channel update, and there is no group policy to retain the old behavior. “We’re simplifying security while strengthening protection through Windows Hello and platform capabilities,” a Microsoft spokesperson told Windows News.

How Device Authentication Replaces the Master Password

After the update, any attempt to edit, view, or export saved passwords will trigger a Windows Hello prompt—whether facial recognition, fingerprint scan, or a PIN. If your device doesn’t support Windows Hello, Edge will fall back to your system password (the one tied to your Microsoft account or local user account). The core idea: your device’s login mechanism becomes the gatekeeper for your saved credentials.

Under the hood, Edge uses the Data Protection API (DPAPI) on Windows, which encrypts data with keys tied to your user account. Previously, the Custom Primary Password added an additional encryption layer using the password you created. Now, that extra layer is gone; the encryption relies solely on your Windows credentials and the device’s Trusted Platform Module (TPM) where available.

When syncing passwords across devices using your Microsoft account, the encrypted payload is transmitted via Microsoft’s servers. However, decryption on each device still depends on local authentication. This means that even if someone compromises your Microsoft account online, they cannot retrieve your password list without also gaining physical access to one of your trusted devices and logging in as you.

Why Microsoft Is Making This Change

The decision reflects several converging trends in cybersecurity and Microsoft’s product strategy:

  1. Push toward passwordless authentication: Microsoft has been phasing out traditional passwords altogether with initiatives like passkeys and Windows Hello. Maintaining a separate master password for a browser feature runs counter to that vision. By tying everything to biometrics or a PIN, Microsoft encourages users to adopt more modern, phishing-resistant methods.
  2. Reducing attack surface: A Custom Primary Password, like any password, can be weak, reused, or forgotten. Users often set it to a simple word because they had to remember it in addition to their Windows password. Microsoft’s own telemetry likely showed low adoption and frequent lockouts due to forgotten master passwords, leading to support burden.
  3. Alignment with Chromium and Chrome: Google Chrome never offered a separate master password; it long relied on the operating system’s credentials store (Keychain on macOS, Linux password managers, and yes, Windows account credentials on Windows). By converging with Chromium’s model, Microsoft reduces code divergence and maintenance overhead while giving users a consistent experience.
  4. Enhanced security with TPM-backed Windows Hello: Unlike a password that can be phished or keylogged, Windows Hello uses asymmetric keys stored in the TPM. Even if malware captures your keystrokes, it cannot intercept a face or fingerprint authentication. The PIN is device-specific and useless on other machines.

What This Means for You: Practical Impact

If You Currently Use a Custom Primary Password

As soon as the update installs, Edge will stop asking for that master password. Instead, you’ll see Windows Hello prompts. Your saved passwords remain intact—they are not lost or exposed. The transition should be seamless in terms of data preservation. However, you may need to set up Windows Hello if you haven’t already. Edge will likely display a prompt guiding you to do so after the update.

If You Share Your Computer

This is the biggest pain point. Previously, you could lock Edge’s stored passwords behind a password that a family member didn’t know, even if they knew your Windows PIN. Now, anyone who can sign into your Windows account can potentially view all your saved logins. Microsoft’s solution: use separate Windows user accounts for different people. But for quick shared access on a home PC, that adds friction. Alternatively, you could avoid saving sensitive passwords in Edge and use a dedicated password manager that supports a master password (e.g., 1Password, Bitwarden, KeePass).

If You Have No Windows Hello Hardware

Older PCs may lack a fingerprint reader or IR camera. In that case, Edge will prompt for your system password—the same one you type when you sign in. That could be weaker if you use a simple password or PIN. Microsoft encourages enabling a strong PIN (which is device-bound) rather than a password that can be used across devices. However, the system password fallback still ties to your Microsoft account, which may be protected by multifactor authentication.

Enterprise and Education Environments

IT admins managing Edge via group policies have no policy to keep the Custom Primary Password. They will need to ensure that Windows Hello for Business or other FIDO2 solutions are deployed if they want to maintain strong, multi-factor access to saved credentials. Organizations using shared workstations may need to tighten access controls or move to dedicated password management tools.

The Security Trade-Off: Is It Actually Safer?

At first glance, removing a security layer seems like a downgrade. But a closer examination reveals a more nuanced picture.

For the Custom Primary Password:
- It provided an air-gap between OS access and browser secrets. If someone shoulder-surfed your Windows PIN, they still could not open Edge passwords.
- It could be made very long and unique, possibly random, stored only in your memory—ideal for highly sensitive accounts.
- However, it was often a memorized string that could be phished remotely via social engineering. It also didn’t benefit from hardware-bound attestation.

For Windows Hello / device authentication:
- Biometric data stays local and is never transmitted over the network. The authentication is mathematically unphishable in the traditional sense.
- The PIN is device-specific; even if stolen from Microsoft’s servers, it’s useless elsewhere.
- TPM-backed keys ensure that the password vault can only be decrypted on the exact device where it was created, unless synced decryption keys are somehow extracted—which is extremely difficult.
- A potential downside: if someone has physical access to your unlocked device, they instantly have access to everything. But if your device is compromised at that level, you have bigger problems.

In essence, Microsoft is betting that the physical security of a modern Windows device (with TPM, secure boot, and bitlocker) plus biometrics is more reliable than a user-chosen secondary password. It’s a wager that aligns with the industry’s direction, but it won’t please everyone.

User Reactions and Community Feedback

According to early discussions on the Microsoft Edge Insider forums and Reddit, the reception is mixed. Some users welcome the reduction in complexity: “I always forgot the custom password anyway, and Windows Hello is so fast,” commented one Redditor. Others express frustration: “I used a long custom password so my kids couldn’t access my work credentials. Now I’ll have to use a separate profile or a third-party password manager.”

Power users are particularly vocal, pointing out that Firefox still offers a Master Password and that third-party managers provide better flexibility. “It feels like Microsoft is forcing its ecosystem on us,” a user posted on the Windows News forum. “What if I want to keep my passwords truly separate from my OS login? Now I have no choice.”

Microsoft’s response, as seen in support documentation, emphasizes the enhanced security of Windows Hello and the ability to use passkeys for websites that support them—which bypass stored passwords entirely. The company encourages users to adopt passkeys as the ultimate solution.

The Bigger Picture: Edge’s Password Manager in a Passkey World

This change isn’t happening in a vacuum. Edge is aggressively pushing passkeys—a FIDO2 standard that replaces passwords with cryptographic key pairs authenticated by biometrics. With passkeys stored in the device’s secure enclave, there’s no password to protect. The Custom Primary Password becomes irrelevant for passkey users.

Edge already supports passkeys on Windows, and with the 2026 update, it will likely tighten the integration. In the long run, Microsoft envisions a world where web authentication involves no passwords at all, and the browser simply brokers the authentication using your Windows Hello credentials. Removing the separate master password is a step in that direction, simplifying the user model and reducing potential friction.

How to Prepare for the Transition

  1. Enable Windows Hello if you haven’t already. Set up a PIN (at minimum) and, where possible, fingerprint or face recognition. Go to Settings > Accounts > Sign-in options.
  2. Ensure your PIN is strong. While a PIN is local, a simple “1234” is vulnerable to brute-force on the device itself. Use at least six digits, and avoid obvious sequences. You can also use a password as your sign-in method, but that’s less convenient and secure than Windows Hello.
  3. Review your saved passwords. Consider which ones are highly sensitive and whether they truly need to be stored in a browser. Maybe it’s time to migrate some to a dedicated password manager with a master password, or to adopt passkeys.
  4. Set up separate Windows accounts for family members if you share a PC. That way, each person’s Edge saved passwords remain isolated.
  5. Check your organization’s policies if you’re an IT admin. Plan communication and training for users.

Alternative Browsers and Password Managers for the Disaffected

If you’re unhappy with Edge’s decision, you have alternatives:

  • Google Chrome behaves similarly, prompting for your OS password on Windows and macOS, though it offers no master password option.
  • Mozilla Firefox continues to support a Master Password that locks the credential store separately from your OS login.
  • Brave, Vivaldi, and Opera generally follow the Chromium pattern without a master password.
  • Dedicated password managers like Bitwarden, 1Password, and KeePass provide strong master password options, cross-platform sync, and often free tiers.

For those with stringent security requirements, a purpose-built password manager is usually the better long-term solution anyway, as it offers finer control, auditing, and emergency access features.

Final Thoughts

Microsoft Edge’s removal of the Custom Primary Password marks the end of an era for one of the browser’s more niche security features. For the vast majority of users who never enabled it, nothing will change; they’ll continue using Windows Hello to access passwords as before. For the minority who relied on that extra layer, June 4, 2026, will be a day to either adapt by embracing Windows Hello or explore other tools.

While the move is likely to generate some backlash, it is consistent with the industry’s trajectory toward zero-trust, device-bound authentication. The real question is whether users are ready to trust their entire digital identity to a single device and a fingerprint. Microsoft is betting they are.
