## Biometric Authentication

Biometric authentication uses unique biological traits, such as fingerprints or facial recognition, to verify a user's identity. In the context of high-stakes financial derivatives trading, this method provides a superior layer of security compared to traditional passwords or private keys.

By linking an account to a physical person, it significantly reduces the risk of account takeover and identity fraud. This technology is increasingly being integrated into trading interfaces to ensure that the individual executing trades is indeed the authorized account holder.

It enhances the overall security posture of platforms, fostering trust among institutional and retail participants alike.
