Which step in the Five Steps to Authentication involves physical tokens or devices?

In the context of the Five Steps to Authentication, "Something you have" specifically refers to the use of physical tokens or devices. This category includes items such as smart cards, key fobs, or mobile phones that generate one-time passwords. These physical tokens provide an additional layer of security by ensuring that only individuals in possession of the token can access the system or information.

This method relies on the principle that possession of a specific physical object can prove identity. For example, an employee might use a smart card to gain access to a secure facility or enter a password that is only applicable if they have their token on hand. It enhances security protocols significantly, as it combines something a user knows (like a PIN or password) with something they have (the physical token), making unauthorized access more challenging.

The other options refer to different types of authentication factors: "Something you know" pertains to knowledge-based factors like passwords; "Something you are" includes biometric identifiers such as fingerprints; and "Somewhere you are" relates to location-based factors that might determine access. Each of these has its own purpose, but for the question specifically, "Something you have" directly aligns with the usage of physical tokens or devices.
