    Passkeys are unrelated to the registry, so I can't imagine what you downloaded or what effect it might have on your computer.

    In fact, passkeys are not part of Windows, and Windows has no access to your passkeys. They are stored in the TPM, completely separate from the rest of the computer.

    To create a passkey, go to the log in page of a website that offers passkeys to you. The web page will ask if you want to create a passkey - say yes and the web page will take care of all the complexity.

    The next time you want to log in at that website, simply go to the login page and you'll be prompted to use your passkey.

    I have created passkeys (in 25H2) for every website that offers them to me, including my Microsoft account. I did this because a passkey is so much safer than a password.

    Hi!

    Can you log in using another method, such as a PIN or password? Or are you unable to log in at all? Knowing this helps determine whether or not you have access to Windows, which can narrow down the potential solutions and diagnostic steps.

    What type of passkey do you use?

    Have you used passkeys before, or is this your first time?

    Try these checks in order:

    1. Verify Windows version and updates
      • Open Settings > System > About and confirm the device is on Windows 11.
      • Open Settings > Update & Security > Windows Update and install all available updates.
      • Some passkey features depend on newer Windows 11 builds and updates.
    2. Check whether the device is managed by an organization
      • Open Settings > Accounts > Access work or school.
      • If the device is connected to a work or school organization, some passkey options can be unavailable.
    3. If passkeys were declined for an app, re-enable access
      • On Windows 11 version 24H2 and later, apps must have passkey privacy consent.
      • Open Settings > Privacy & security > Passkey access.
      • Find the affected app and turn passkey access back on.
      • If consent was previously declined, passkey registration and sign-in will not work for that app until access is allowed again.
    4. Check the sign-in method being used
      • Passkeys on Windows use Windows Hello.
      • If synced passkeys are not appearing, make sure the device has a screen lock available, such as PIN, face, or fingerprint. Passkeys cannot be used on a device without face, fingerprint, or PIN authentication.
    5. If the problem happens during cross-device sign-in
      • Make sure Bluetooth is enabled on both devices.
      • Make sure both devices are connected to the internet and are near each other.
      • Cross-device passkey sign-in can fail if Bluetooth is off or hanging.
    6. If this is a new PC or a new Windows installation
      • Passkeys may need to be set up again on the new device.
      • After setting up new passkeys, old passkeys that no longer apply can be removed from the account.
    7. About the registry fix already tried
      • The provided context includes a registry workaround for a specific Windows issue, but it does not state that it fixes all Windows 11 25H2 passkey problems.
      • Registry editing is risky and can cause system issues if done incorrectly.

    If the issue is that passkeys do not open at all in multiple apps, the most relevant Windows-side checks from the available guidance are: Windows fully updated, Windows Hello/PIN available, app access allowed under Privacy & security > Passkey access, and no work/school management restrictions.
