Biometric Authentication
Also known as: Biometrics, Biometric Login
User identity verification via unique biological traits, integrated with crypto wallets.
Biometric Authentication uses unique human characteristics—like fingerprints, facial recognition, or iris scans—to authenticate users. In Web3, biometric methods are being integrated with wallets and devices to improve security and user experience. Biometric data can provide passwordless login, transaction approvals, and key recovery mechanisms, while maintaining privacy through local storage or zero-knowledge proofs. This enhances security but requires careful handling of biometric data and compliance with privacy standards like GDPR.
