Biometric Authentication vs Passwords

Biometric authentication uses physical characteristics — fingerprints, face, or iris — to verify identity. While convenient, biometrics and passwords have different security trade-offs.

Key Differences

• Biometrics: Cannot be changed if compromised. Convenient for device unlock. Vulnerable to physical coercion.
• Passwords: Can be changed if leaked. Requires memory or a password manager. Vulnerable to phishing and brute force.

Best practice: Use biometrics as a convenient layer for device access, combined with a strong password and 2FA for account authentication.
