What if my device does not support Bluetooth or QR codes?

Passkeys can leverage hybrid transport methods, such as Bluetooth (caBLE) and QR codes, for cross-device authentication. However, if your device does not support either, you still have several options for secure authentication.

If your device lacks Bluetooth or a QR scanner, you can use one of these alternative methods:

• Synced Passkeys: If your passkeys are stored in a cloud service (e.g., iCloud Keychain, Google Password Manager), they will be available across all your devices logged into the same account.
• Hardware Security Keys: Devices that do not support passkey transport via Bluetooth or QR codes can authenticate using FIDO2-compliant hardware security keys, such as YubiKeys or Titan Security Keys.
• Platform-Specific Authentication: If your device supports WebAuthn but lacks Bluetooth or a camera, you can use biometric authentication methods like Windows Hello, Face ID, or Touch ID.
• Manual Credential Transfer: Some organizations provide a manual fallback method to transfer authentication information securely between devices.

If you frequently encounter passkey authentication issues due to missing Bluetooth or QR support:

• Enable cloud sync for passkeys within your ecosystem (Apple, Google, Microsoft).
• Keep a backup authentication method, such as a hardware security key.
• Ensure your WebAuthn settings allow for multiple authenticators, so you are not locked out if a single method fails.

While hybrid transport (QR codes and Bluetooth proximity checks) enhance security and usability, WebAuthn ensures that users can still authenticate even if their device lacks these features.
