Microsoft Edge Adds Passkey Support and Syncing with Password Manager

Microsoft Edge now makes it possible to securely save and sync passkeys using Microsoft Password Manager, providing a new passwordless way to sign in to supported websites and applications. This update works on Windows devices (10 and above) with Edge version 142 or newer and a Microsoft account.

What Are Passkeys?

Passkeys are a modern authentication method based on the FIDO2 standard, leveraging public-key cryptography. When a passkey is created, your device generates a unique private key (stored securely and never leaves your device) and a public key (shared with the website). Authentication relies on biometrics (fingerprint, face recognition), or a device PIN, reducing exposure to credential theft.

  • Cannot be guessed or reused like passwords
  • Resistant to phishing and credential attacks
  • No need to memorize or type complex passwords

How it Works in Microsoft Edge

  • You can save passkeys in Microsoft Password Manager when signing in to supported websites.
  • Passkeys sync securely with your Microsoft account and protected by a dedicated Microsoft Password Manager PIN set up during initial passkey creation.
  • To use passkeys on another device, you verify yourself with the Manager PIN.
  • Passkeys are managed from Edge (Settings > Passwords and autofill > Microsoft Password Manager).

Security & Privacy Details

  • Passkeys are encrypted in the cloud.
  • All PIN unlock and reset attempts are logged and integrity-protected in the Azure confidential ledger for transparency.
  • Biometric data is always processed locally, not shared with websites or Microsoft.
  • If you forget your Manager PIN, it can be reset from any device with active passkey access.

Prerequisites

  • Windows device running version 10 or above
  • Microsoft Edge version 142+
  • Microsoft account

Additional Notes

  • Passkey sync is not yet available on mobile or for Microsoft Entra accounts.
  • Microsoft Password Manager plugin will extend passkeys to other apps and browsers on Windows in future updates.
  • Saved passwords remain untouched; passkeys are an added option for supported sites.
  • More technical details and documentation are available for Azure confidential ledger.

Frequently Asked Questions

  • Does this impact my existing passwords? No, you can continue using them or upgrade to passkeys for supported sites.
  • What if my device is lost or stolen? Biometric/PIN security prevents unauthorized access to passkeys.
  • Can passkeys be used outside Edge? Support for other browsers and apps is coming soon via plugin.
  • Is business/school account support included? Not yet; currently limited to personal Microsoft Accounts on Windows.
