Biometric authentication uses unique physical characteristics, such as fingerprints, facial recognition, voice recognition, or iris scans, to verify a person's identity.
It is now widely adopted due to the widespread use of smartphone devices which is now equipped with biometric sensors, such as fingerprint scanners and front-facing cameras.
🔒 INCREASED SECURITY: Physical traits are harder to replicate or steal as compared to PIN codes and passwords.
👍 CONVENIENCE: Biometric authentication enables password-less authentication — which does not require users to remember complex passwords or carry around physcial tokens.
👟 SPEED: Biometric authentication is faster than traditional authentication methods, as it typically only takes a few seconds to scan and verify a user's biometric data.
🦼 ACCESSIBILITY: Biometric authentication can be more accessible for users with disabilities, as it does not require manual dexterity or the ability to remember and type in passwords.
Standalone biometric authentication should only be used for low-risk actions, such as account logins or balance checks. To perform high-value tasks, such as password changes or account trasnfers, It needs to be combined with other authenticaiton systems, such as OTP and eKYC to enable multi-factor authentication.
