Identification vs Authentication

 , updated on November 26, 2016
Identification is when someone identifies themselves. For example, entering your user id in a logon form is identification.
Authentication is when a system or process verifies identification.

Identification vs Authentication

Consider employee identification cards. Wearing a photo id with your name on it is an act of identification. As you walk around the office, people can see that you are claiming to belong to the organization.
Scanning your employee identification card at the entrance to the office and entering a password is an example of authentication. The system verifies your identification by confirming the validity of the id and password. Such authentication systems might also require a fingerprint scan.
