The feature now works using Chrome on both desktop and mobile running Windows 11, macOS, and Android. Google also lets you sync passkeys from Android to other devices through either the company’s own password manager or a third-party one that supports it, like 1Password or Dashlane.
A passkey is a unique identity that’s stored on your computer, phone, or other device like a USB security key. For websites or applications that have implemented the passkey API, it can let you log in through a simple and quick confirmation combined with your device’s biometrics or other secure authentication.
The usefulness of passkeys in Chrome — and other browsers — will come down to sites implementing the WebAuthn API to accept passkeys. Some banking sites like Tribank have already added it, and other services like PayPal also have it enabled.
