What is an identity control token?

An identity control token is defined as a physical device code or characteristic used to confirm identity. This type of token serves as a secure method for authenticating a user’s identity by providing a unique identifier that is difficult to replicate. It could be in the form of a hardware token, like a key fob or smart card, which generates a code that is used during the log-in process.

This approach enhances security by adding an additional layer beyond just knowledge-based authentication methods, such as passwords. By requiring something the user has (the physical token), systems can reduce the risk of unauthorized access that often occurs through stolen or easily guessed passwords.

The other options represent methods of identity verification but do not encapsulate the specific definition and function of an identity control token. Software applications and passwords are more focused on knowledge or digital means of verification, while access cards primarily provide physical entry to a location rather than a specialized identity verification function.
