Online identity verification technology typically utilizes biometric authentication, two-factor authentication (2FA), and identity verification services. Biometric methods include fingerprint scanning, facial recognition, and voice verification, which accurately confirm an individual's identity. Two-factor authentication adds an extra layer of security by requiring users to provide a second form of identification, such as a one-time code sent to a mobile device. These technologies combine to enhance security and trust in online transactions, protecting both users and organizations from identity theft and fraud.
