How to Sync Passkeys Securely Across Devices

Passwords are still one of the biggest causes of security risk and user frustration today. If you want to sync passkeys securely, Microsoft Edge now offers a simpler and safer way to log in across devices without relying on traditional passwords.

What are passkeys and how do they work?

Passkeys let you sign in without typing a password by using your device identity instead. Your fingerprint, face, or PIN proves who you are, while a secure key stored on your device handles authentication behind the scenes.

Passkeys use the FIDO2 standard, which removes the need for shared secrets. That means nothing sensitive is sent over the internet during login. Instead, your device confirms your identity directly with the service you are accessing.

This approach is far more secure because attackers cannot steal or reuse what never exists. It also improves usability, as users do not need to remember or reset passwords.

Why was storing passkeys on one device a problem?

Single device passkey storage created a real risk of account lockout and user frustration. If a device was lost or replaced, access could be difficult to recover without a backup.

From a business perspective, this created hesitation around adoption. IT teams worried about users being locked out after upgrades or hardware failures. As a result, many organisations kept passwords as a fallback.

That defeats the purpose of stronger authentication. It adds support overhead, increases risk, and slows down users who just want to get on with their work.

How do you sync passkeys securely in Edge?

To sync passkeys securely in Edge, you sign in with your Microsoft Account and enable sync with Microsoft Password Manager. Your passkeys are then encrypted and stored safely in the cloud, ready to use on other trusted devices.

The process is simple and works well for Windows 11 environments:

• Sign in to Edge with a Microsoft Account
• Turn on sync in browser settings
• Enable Microsoft Password Manager
• Choose “Save as passkey” when prompted
• Access passkeys on another device securely
• Unlock with PIN or biometric check

Once set up, your credentials travel with you securely. That makes device changes and hybrid work much easier to manage.

Is cloud passkey sync in Edge secure?

Yes, cloud synced passkeys are designed to be as secure as device only storage, with added flexibility. Microsoft protects passkeys using encrypted storage and layered authentication controls.

Your access relies on several protections working together:

• Microsoft Account sign in
• A second factor such as a PIN or biometric
• Encryption of data at rest in the cloud

Even if a device is compromised, attackers still need to pass multiple layers of authentication. More importantly, passkeys remove common risks such as phishing and password reuse.

How does passkey syncing help your business?

Passkey syncing improves both security posture and productivity across your team. It reduces reliance on passwords while making access faster and more consistent.

Here are the key business benefits:

• Fewer password resets and service desk tickets
• Reduced phishing risk due to passwordless login
• Faster onboarding for new devices and staff
• Stronger compliance with modern security standards
• Better experience for remote and hybrid users

These gains are small individually but significant at scale. Over time, they reduce IT overhead and improve day to day operations.

When will passkeys work on all devices?

Passkey sync is already available in Edge on Windows 11, with wider support expanding steadily across platforms. Microsoft continues to roll out support for additional devices including mobile and Mac environments.

You will see increasing adoption across websites and services as passkeys become more common. In many cases, users are already being prompted to save passkeys instead of passwords.

For now, Windows 11 remains the primary platform for full passkey sync capability.

What should you do now about passkeys?

Start using passkeys in a controlled way to understand the benefits and rollout process. Begin with a small group of users and expand as confidence grows.

A practical approach includes:

• Testing passkeys on key systems
• Updating internal security policies
• Training staff on how passkeys work
• Encouraging users to save passkeys where possible

If Edge offers to save a passkey, it is usually the right choice. Over time, this builds a more secure and seamless login environment across your business.
