Biometric authentication is a security protocol for online card payments that require authentication where you can use a biometric factor (like a fingerprint or facial scan) to verify your identity, adding a secure layer of protection to reduce fraud. This authentication happens when your bank or issuer requires verification, redirecting you to a secure screen to complete the biometric scan, which is then relayed to confirm the transaction is initiated by the rightful owner.
