1) Errors: Fingerprint scanners or facial recognition might not work perfectly every time.

2) Workarounds: Someone with access to your phone (which might hold your fingerprint) could still potentially gain access.

• The Ideal Combination: Biometrics are often combined with passwords or other factors (like a code from your phone) in Multi-Factor Authentication (MFA).

• Stronger Defence: MFA makes it much harder for unauthorized access, even if a password is compromised.

• Data Storage: How securely is your biometric data stored? Breaches can expose this sensitive information.

• Liveness Detection: Some systems can be fooled by pictures or videos. Liveness detection helps ensure a real person is presenting the biometric data.

Biometrics and passwords are increasingly used together. This two-factor authentication provides a stronger security layer. Even if a hacker steals your password, they would still need to bypass the biometric scan to gain access.

Remember, biometrics isn't a foolproof solution, but it offers a convenient and secure way to enhance password security, especially when combined with strong password practices.
