===Security token===
{{Main|Security token}}

Some online sites offer customers the ability to use a six-digit code which randomly changes every 30–60 seconds on a physical [[security token]]. The token has built-in computations and manipulates numbers based on the current time. This means that every thirty seconds only a certain array of numbers validate access. The website is made aware of that device's serial number and knows the computation and correct time to verify the number. After 30–60 seconds the device presents a new random six-digit number to log into the website.<ref>{{cite web|url=https://searchsecurity.techtarget.com/definition/security-token|title= What is a security token?|publisher=SearchSecurity.com|author=Margaret Rouse|date=September 2005|access-date=2014-02-14}}</ref>
