Security is ever more critical in today's modern digital world. One way society is maintaining security standards is via Two Factor Authentication. Two Factor Authentication, or 2FA, is an additional means of security by which users combine two different components of identification. It requires that a user provide a secondary piece of information alongside their usual standard method of access to accounts, etc.
2FA will be familiar to many in the processing of online payments, whereby an SMS code is sent to be used to complete a transaction.
Two-factor authentication is a method of identity verification using two different factors; any combination of knowledge, possession or inherent factors. Two-factor authentication is a subset of multi-factor authentication, which uses a combination of multiple factors for verifying or authenticating user identity.
These are the most common methods of identity authentication, through answering of a question that only the user should know the answer to - for example a password they previously chose, the PIN to their bank card, the answer to a predefined security question (eg. mother’s maiden name or first pet name). The latter can be a poor form of authentication as such questions may be widely known about the person.
An inherent authentication factor makes use of something only the user has - like a fingerprint, facial recognition or voice recognition. They tend to be most often biometric methods.
The most basic case of authentication by possession is a key and a lock - those who are without the possession of the key are unable to open the lock. These days people can carry a security token or download mobile authentication apps to perform possession authentication. SMS authentication is another type of possession authentication, as the user must have access to the correct mobile handset.
A one-time password is a common 2FA tool. One time passwords (OTP) are valid for a single login session on a computer or other digital device. They provide an extra level of security, as they are not vulnerable to being recorded and replayed for logging into a service illegally.
One time passwords are much more digitally secure than using user-nominated passwords; they are unique to every single user and every single session, and expire after only a very short time. An SMS generated one time password, or SMS OTP, is a popular and ever more common 2FA solution that offers the convenience of an app-based security module but without any requirement for downloading software or new systems for operation.
