Which term refers to proving your identity online?

The term that refers to proving your identity online is authentication. Authentication is the process through which an individual’s claimed identity is confirmed, usually through the use of credentials such as passwords, biometrics, or security tokens. This process ensures that the person attempting to access a system or service is indeed who they say they are.

In the context of online security, authentication is a critical component, as it safeguards sensitive data and helps prevent unauthorized access to systems. Strong authentication measures are essential for maintaining security in various online services, including banking, social media, and cloud services.

The other terms mentioned relate to various aspects of security but do not specifically address the process of confirming identity. Authorization pertains to granting permissions to users based on their identity and access levels after authentication has occurred. Validation usually refers to checking whether data entered into a system meets certain criteria, and verification generally involves confirming the accuracy of information or claims, but does not specifically relate to identity confirmation online.
