"Digital authentication" involves verifying the identity of individuals or systems trying to access digital resources or applications. It typically uses methods such as passwords, biometrics, or multi-factor authentication (MFA) to ensure that only authorized users gain access. Digital authentication is essential for protecting sensitive information and maintaining security within online transactions. It plays a crucial role in reducing identity theft and unauthorized access, building user confidence in digital platforms. Effective digital authentication mechanisms are vital in today's cybersecurity landscape, where threats are continuously evolving.
