Hewden, the United Kingdom’s largest rental company, last week announced it will use a mobile phone security token system to protect its corporate systems when data is accessed remotely.

SecurAccess is a two-factor authentication system that uses mobile phones as virtual tokens, which eliminates hardware and deployment management problems, and prevents keylogging attacks.

The system works by sending a one-time pass code to a worker’s mobile phone, allowing them to use the corporate system remotely. The user then enters his or her standard user name and password, as well as the pass code from their mobile phone. Once that pass code has been used, a new one is sent and the previous pass code is overwritten.

According to Hewden, using SecurAccess will save the company between 50 and 60 percent off the cost of using a hardware token because the license is cheaper.
