Question

I don’t know what these are called, so I will explain as best I can what we want to do:

We want to implement a secure log-in system so that when logging in we want to ask for a number that is generated on a small device that is carried with the person at all times.

I understand these devices work by relying on an algorithm that generates random numbers based on the current time. The same method is used on the sever side. They both independently generate the same numbers, since their clocks are in sync, and because its the same algorithm. When the user enters this number they should match.

Where can one buy these security dongles? What is this authentication method even called?

Answer 1

I know of RSA SecurID as a supplier of two-factor authentication solutions.
