What is a hard token?
A hard token, sometimes called a security key, is a physical device that functions like a key for gaining access. It is a physical device that helps verify your identity or log onto a system like a personal computer, hosted software application, network, or other electronic device. Hard token devices store authentication secrets or passcodes in a digital format.
What does a hard token look like?
There are a variety of hard tokens available on the market, but most are small and designed to be carried like key fob. Typically, a hard token device is around two to three inches long. Some hard tokens can be inserted directly into a computer like a USB device. Other hard tokens are small pieces of hardware with a small screen that displays security passcodes that you use to complete authentication.


How do hard tokens work?
Hard tokens are most often used for multi-factor authentication (MFA). You can pair your hard token with a password to sign into a device, software application or website. USB type hard tokens, when inserted into a device, pass on a secret piece of information that is unique to that hardware device for authentication purposes. USB type hard tokens can also support password-less login.
Hard tokens designed with a screen, generate then display a unique, one-time code that you enter along with your password on a login page. The user may have to click a button on the hard token to generate a new passcode.
Because hard tokens are a physical device that often work offline, they are generally considered very secure against online threats like phishing and malware. Hard tokens make multi-factor authentication easy and secure, they help protect your personal data and prevent hacks or account take overs.
