However, it also raises privacy concerns. Biometrics can still be hacked and organizations that store users’ personal information tend to be under constant threat from hackers. - **What are some common uses of biometric authentication?**Biometric authentication is commonly used in smartphones, access control systems, and secure government facilities to verify identities. It is often used as a second layer of security to prevent accounts from being easily hacked. 1.
