Microsoft Edge is enhancing online security with the introduction of passkey saving and syncing capabilities through its Microsoft Password Manager. This update allows users to securely store and synchronize passkeys across their Windows desktop devices, offering a streamlined and more secure login experience. What are Passkeys? Passkeys offer a password-free login alternative, utilizing your device's built-in security features like fingerprint scanning, facial recognition, or PIN. Built on the FIDO2 standard, passkeys use public-key cryptography, enhancing security by storing a unique private key for each website while the website stores only the public key. This significantly reduces the risk of account compromise even in the event of a website data breach. Benefits of Using Passkeys:

Enhanced Security: Passkeys are resistant to phishing and credential stuffing attacks, offering a more robust security layer than traditional passwords.
Simplified Login: Forget complex passwords; use biometric authentication for a faster and easier login process.
Cross-Device Compatibility: Passkeys sync securely via your Microsoft account and are currently available on Windows devices.
Privacy-Focused Design: Biometric data is processed locally, and websites only receive cryptographic proof of authentication.

How to Use Passkeys in Microsoft Edge: Microsoft Password Manager in Edge securely stores passkeys on Windows devices. Passkeys are protected by a Microsoft Password Manager PIN and can be used to log in to supported websites using fingerprint, facial recognition, or a PIN code. Requirements:

Windows 10 or later
Microsoft Edge version 142 or higher
A Microsoft account

Security Measures: Passkeys are stored in the cloud in an encrypted format and are protected by a Microsoft Password Manager PIN. The system logs all PIN unlocking and reset attempts in the Azure confidential ledger for enhanced transparency and security. For users who forget their Microsoft Password Manager PIN, it can be reset from a device with existing passkey access via Edge Settings > Passwords and autofill > Microsoft Password Manager > Settings. FAQ Highlights:

Existing passwords remain untouched and usable.
Passkeys can be added to existing accounts without creating new ones.
Passkeys sync securely via Microsoft account to new devices after PIN verification.
Passkey syncing is currently limited to Windows devices and is unavailable for mobile or work/school accounts.
Passkeys are secure even if a device is stolen, requiring biometric or PIN verification for use.
