Biometric authentication uses a person’s physical or behavioral characteristics to help verify their identity. Fingerprint readers and facial recognition are already common on phones, laptops, and workplace systems. Some technologies can also evaluate a person’s voice, eyes, or the way they type.
Biometrics can make authentication faster and more convenient because employees do not need to memorize or enter another code. They can also reduce reliance on passwords that may be guessed, reused, or stolen.
Biometrics don’t come without risks, though. A biometric is not simply a more advanced password.
If a password is exposed, it can be changed. A person cannot replace a fingerprint or face in the same way. Biometric systems must therefore store and process this information securely.
Attackers may also use photographs, recordings, deepfakes, or other techniques to imitate biometric traits. Secure systems use protections such as “liveness detection” to determine whether the person is physically present, but employees should never assume that biometrics make an account invulnerable.
