No, Singpass does not collect your biometric data when you use your passkey.

When you create a passkey, your device handles all biometric authentication locally to protect your privacy and security.

This means:

• Your biometrics remain private on your device only

• Singpass cannot access or store your biometric information

• No websites or apps can collect your biometric data through a passkey

Your device uses your biometrics to unlock your passkey, but this process happens entirely within your device's secure system. This design ensures your most sensitive personal data stays within your control.
