A Synced passkey is a FIDO standards-based passkey that is securely synchronized across a user’s trusted devices through a cloud-based credential manager.
It replaces reusable passwords with public-key cryptography. The service keeps a public key, while the private credential stays protected by the device, platform, or password manager.
When a user creates a Synced passkey, the app or website registers a public key for that account. The private key is stored in a protected credential manager and made available on eligible devices signed into the same ecosystem or vault.
At sign-in, the user unlocks the credential with biometrics, a device PIN, or platform verification. The private key signs a challenge, so phishing sites and breached password databases cannot reuse it.
| Authentication element | Why it matters |
| Public key | Stored by the app or website and used to verify login challenges. |
| Private credential | Protected by the user’s device, platform, or password manager. |
| Sync fabric | Makes the credential available across approved devices and supports recovery. |
A device-bound passkey stays on one authenticator, such as a hardware key or specific managed device. A Synced passkey can be restored or used across multiple devices through a sync fabric.
This distinction matters for risk. Synced passkeys improve usability and recovery for broad workforce adoption, while device-bound credentials may be better for privileged roles, regulated workflows, or strict key custody requirements.
Hexnode supports Synced passkey adoption by keeping endpoints ready for secure passwordless authentication. Through UEM, IT teams can monitor device inventory, enforce baseline policies, check compliance status, manage OS updates, control approved apps, and apply restrictions across supported devices.
Hexnode does not replace an identity provider or credential manager. It strengthens the managed-device layer around them, so users authenticate from compliant endpoints and administrators can use remote actions, application controls, and security posture management to reduce endpoint drift.
Organizations should use synced passkeys when they want faster sign-ins, fewer password resets, and stronger phishing resistance across trusted user devices.
Before rollout, define who can use them, how recovery works, and whether privileged admins need device-bound credentials. Treat synced passkeys as part of identity and endpoint governance, not a standalone control.
They should be used carefully on shared devices. Organizations should prefer managed profiles, strong local verification, and clear sign-out or device reassignment workflows.
Synced passkeys are a common implementation of syncable authenticators. The broader term can also describe other authenticators whose secrets are securely synchronized between devices.
In many cases, passkeys provide phishing-resistant multi-factor authentication through possession of the device and local user verification, but policy requirements may still vary.
