Multi-Step Authentication and Why You Should Use It

Author: James Michael Stewart

As users of online sites and services, we have no control over the security policies and technologies implemented on those sites and services. At best, we may be offered a few authentication options. If any authentication mechanisms are available in addition to a standard password, you need to take full advantage of those benefits.


Authentication is one of the essential components of security. It is one part of the concept known as authentication, authorization, and accounting (AAA). Authentication is the process of claiming an identity the proving that you are that claimed identity. Authorization is the mechanism to control what you can access or do. Accounting is the recording of events into a log to review the activities against the rules and policies in order to detect violations or confirm compliance. All three of these should be addressed when constructing a system in order to have a reasonable foundation for reliable security.
