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.

Alternative Authentication Methods#

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.

Best Practices for Seamless Authentication#

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.

About Corbado

Corbado is the Authentication Intelligence Platform for CIAM teams running consumer authentication at scale. We help you see what IDP logs and generic analytics tools can't: where passkeys, passwords, OTP, social login and fallback journeys succeed, stall or fail, which devices and browsers create friction, and when an OS update silently breaks login. Two products: Corbado Observe layers process mining and observability across authentication journeys. Corbado Connect adds managed passkeys with analytics built in alongside your IDP. VicRoads runs passkeys for 5M+ users with Corbado (+80% passkey activation). Talk to a Passkey Expert →
