Microsoft Edge is retiring its Custom Primary Password feature on June 4, 2026, pushing all saved-password authentication to device‑based methods like Windows Hello, a device password, or macOS Touch ID. The change eliminates the extra password that many users set up to protect their credential store, and instead ties access directly to the security built into the operating system.

What Was the Custom Primary Password?

Edge’s password manager has long allowed users to save and autofill passwords for websites. For those wanting an additional barrier, the Custom Primary Password was an optional, user‑defined string that acted as a master key. Before any saved password could be viewed or filled, Edge would demand this second password—separate from the Windows login. The feature was especially popular on shared devices or among security‑conscious users who didn’t want anyone with access to their Windows account to also see their web credentials.

Behind the scenes, the Custom Primary Password encrypted the password database with a key derived from that password. The database sat in the user’s profile, encrypted with AES‑256, and without the custom password the contents were a scrambled mess. It was a solid, if old‑fashioned, defense‑in‑depth approach.

What’s Changing on June 4, 2026

Starting with the Edge release that lands on June 4, 2026, the Custom Primary Password toggle will disappear from Settings. Microsoft is removing the option entirely for consumers and enterprises alike. For users who currently have it enabled, their saved passwords will be automatically migrated to the new protection scheme.

The migration process works like this:

  1. After the update, Edge will prompt you one last time to enter your existing Custom Primary Password.
  2. Once verified, Edge decrypts your password database and re‑encrypts it using a key stored in your device’s security hardware—specifically, a key tied to your Windows Hello credentials or device password.
  3. The old encrypted vault is deleted, and from that moment on, any attempt to access saved passwords triggers a device‑authentication prompt.

If you’ve forgotten your Custom Primary Password, the migration cannot proceed. Microsoft warns that in such cases the only option will be to reset Edge’s password store, which erases all previously saved credentials. This is why the company urges users to export their passwords beforehand if there’s any risk of forgetting the custom password.

How the New Authentication Works

Once migrated, unlocking passwords in Edge requires one of these methods, depending on your platform:

  • Windows Hello: facial recognition, fingerprint, or a PIN. The underlying private key never leaves the TPM (Trusted Platform Module).
  • Device password: if your machine lacks biometrics, Edge falls back to the Windows login password or PIN. This is the same credential you use to sign into your PC.
  • macOS Touch ID or system password: on a Mac, Edge will request a fingerprint scan or your local account password.

The experience mirrors what many users already see with apps like password managers or banking software. A quick scan or a short PIN is all it takes to view a password or fill it on a website.

Why Microsoft Is Making This Move

The decision isn’t a random rollback—it’s part of a broader industry shift toward hardware‑backed authentication. A custom primary password, while better than nothing, suffers from several weaknesses:

  • It can be weak or reused, negating its purpose.
  • It’s stored (hashed) inside the user profile and could be targeted by malware that attempts offline cracking.
  • It relies entirely on the user remembering yet another secret, leading to password fatigue and support tickets.

Windows Hello and similar platform‑authenticators are resistant to these problems. Windows Hello, for example, uses asymmetric cryptography: a public‑private key pair is generated inside the TPM during enrollment, and the private key is sealed with your biometric data or PIN. The private key never exists in plaintext outside the TPM, and even an attacker with full filesystem access can’t extract it. When you autofill a password, Edge asks Windows to prove your identity using that key, and Windows responds only after you’ve successfully passed the biometric or PIN challenge. The process is phishing‑resistant and immune to most common forms of credential theft.

Microsoft’s broader passwordless vision also plays a role. The company is betting on passkeys and the FIDO2 standard, where the device itself authenticates you to websites. Tying Edge’s password manager to the same hardware anchor moves one step closer to a world where you never have to remember a password at all.

Impact on Different User Groups

Everyday Consumers

For the vast majority of people who use a single Windows account on a personal laptop, the change is a net positive. Opening a stored password becomes as simple as looking at the camera or touching a fingerprint sensor. No more fumbling with a long master password that you’ve inevitably forgotten. Security is actually improved because the cryptographic binding to hardware makes remote attacks much harder.

Privacy‑Conscious and Shared‑Device Users

This group loses a valued isolation layer. The Custom Primary Password meant that even if someone had physical access to your signed‑in Windows session (e.g., you left your desk without locking), your web passwords stayed locked behind an extra secret. Now, anyone who can sit at your unlocked PC and authenticate with the same device method—which might be your face or your PIN—can use your saved passwords.

Microsoft’s answer is to encourage the use of separate Windows accounts for each user and to lock the device when stepping away. Both are standard security hygiene, but many home users don’t follow them. In corporate settings, IT admins may need to enforce stricter auto‑lock policies and disable password saving on shared terminals.

Enterprise and Education Environments

Organizations that relied on the Custom Primary Password as part of their security stack—for example, to meet a regulatory requirement for an extra password—will have to adjust. Edge’s group policy templates do not offer an equivalent replacement. Administrators can either:
- Enforce Windows Hello for Business, which provides strong, policy‑managed authentication.
- Use third‑party password managers with their own master‑password mechanism.
- Disable Edge’s built‑in password manager entirely and rely on corporate single sign‑on.

Microsoft may release additional guidance before the deadline, but for now companies should start planning their migration.

Mac Users

On macOS, Edge will use Touch ID or the device password, drawing on the Secure Enclave in the same way Safari and other Chromium‑based browsers do. The experience is consistent with what Mac owners already expect. The only caveat: if you previously used a Custom Primary Password, export your data before the migration, because macOS recovery procedures can’t rescue an Edge password vault that still requires a forgotten custom password.

Step‑by‑Step Preparation Guide

If you’re among the users who opted into the Custom Primary Password, here is exactly what you should do before June 4, 2026:

  1. Verify your current setup
    - Open Edge and go to edge://settings/passwords.
    - If you see a “Require authentication” entry labeled “Custom primary password”, take action.

  2. Export your passwords immediately
    - Still on the passwords page, click the three‑dot menu and choose “Export passwords”.
    - Save the CSV file in a secure location. This is your safety net if anything goes wrong during migration.

  3. Set up or strengthen Windows Hello
    - On Windows, go to Settings > Accounts > Sign‑in options.
    - Enroll a PIN, face, or fingerprint. Ensure the option “Require Windows Hello sign‑in for Microsoft accounts” is enabled for maximum security.
    - On macOS, verify Touch ID is configured in System Preferences.

  4. Consider a dedicated password manager
    - If you still want a master‑password concept, tools like Bitwarden, 1Password, or Dashlane let you lock your vault with a strong password while also supporting biometric unlock.
    - Import the CSV you exported from Edge into your chosen manager.

  5. Once the update arrives
    - When Edge prompts for your old Custom Primary Password, enter it carefully. If you’re unsure, use the exported CSV to restore your passwords later rather than guessing and risking a lockout.
    - After migration, visit a few saved‑password sites to confirm autofill works. If anything is missing, re‑import the CSV.

Security Analysis: Better or Worse?

Security experts are split, but the technical merits lean in favor of the new design for most scenarios.

Strengths of device‑only authentication:
- Hardware‑backed keys resist extraction; even a total system compromise won’t expose the raw encryption key.
- No extra password to phish—users see the genuine Windows Hello prompt, which has anti‑spoofing protections.
- Biometrics and PINs are faster, reducing the temptation to leave the vault permanently unlocked (a common problem with master passwords).

Weaknesses:
- Single‑factor device access: if someone obtains your PIN or forces you to unlock via biometric coercion, all passwords are exposed.
- Shared accounts become more dangerous, as noted above.
- Users who were happy with the current system may feel forced into a change they didn’t ask for.

In practice, the Custom Primary Password’s security relied heavily on its secrecy and complexity. Many users chose something weak or reused from another service, undermining its value. Windows Hello’s PIN, in contrast, is at least 4 digits and protected by TPM anti‑hammering (the TPM locks after too many wrong attempts). And a well‑trained facial‑recognition system is far harder to fool than a password is to shoulder‑surf.

What About Password Sync and Microsoft Account?

Edge syncs passwords across your devices when you sign in with a Microsoft account. Those passwords are encrypted end‑to‑end, and Microsoft doesn’t hold the keys. With the Custom Primary Password gone, the sync‑layer protection remains the same: the vault is encrypted with your Microsoft account credentials plus, optionally, a recovery code. The removal of the local custom password does not weaken the cloud‑sync security model; it only changes how the local vault is unlocked.

Community Reaction

Early forum discussions reveal a mix of relief and frustration. Some users who had repeatedly locked themselves out of their own password store welcome the move, calling it “long overdue” and a “sensible simplification.” Others, particularly those who manage family PCs where multiple people share one account, worry that “Microsoft is removing a security feature without giving us an alternative.” A few enterprise administrators have voiced concerns on Tech Community threads, requesting a Group Policy that forces an additional PIN or the ability to require Windows Hello every time—something that is already possible via Windows Hello policies but may need clearer documentation.

One frequently mentioned tip is to use Windows’ Dynamic Lock feature, which automatically locks the PC when your paired phone walks out of Bluetooth range. Combined with a strong Hello PIN, this can mitigate some of the shared‑session risks.

Alternatives if You Don’t Like the Change

If you absolutely require a master‑password setup, you are not locked into Edge’s native manager. All Chromium‑based browsers support third‑party password managers that can fill credentials seamlessly. Options include:

  • Bitwarden (open source, self‑hostable)
  • 1Password (polished UI, travel mode)
  • KeePassXC (local database, fully manual)
  • Dashlane (built‑in dark‑web monitoring)

Each of these vaults is protected by a master password and, optionally, a biometric unlock. Edge can automatically import your saved passwords during setup, or you can manually export/import the CSV file.

Looking Ahead

The death of the Custom Primary Password is a small but telling step in Microsoft’s journey toward a passwordless ecosystem. Edge will soon integrate more deeply with passkeys stored in Windows Hello, and the line between the browser’s password manager and the OS credential store will blur further. The company wants you to think of authentication as something that happens because of who you are (biometrics) or what you have (a secured device), not what you can remember.

For Windows enthusiasts, the change might feel like a loss of a nerdy security knob, but it’s also a sign that hardware‑backed security is finally mature enough to be the default. The challenge for Microsoft will be communicating the benefits clearly and giving enterprises the tools they need to maintain compliance.

June 4, 2026 will be a pivotal date for anyone who still relies on that extra password. Prepare now, export your data, and take a few minutes to set up Windows Hello if you haven’t already. The future of password management is already here—it just requires a different kind of trust.
