Free and Secure Internet
Many online sites offer clients the ability to use a X-digit code which randomly changes every 30-60 seconds on a security basis. The key on the security token have mathematical computations built-in and manipulate numeric based on the present time built into the device. That means that every thirty seconds there's only a certain possible array of numbers which would be correct to validate access to the online A/C. The site that the user is logging into would be made aware of that devices' serial number and therefore would know the computation and correct time built into the device to verify that the number given is in deed one of the handful of six-digit numbers that would work in that given 30-60 second cycle. After the 30-60 seconds the device will present a new randomly six-digit number which can log into the webpage. For more about using numbers in Database visit here.
