Is SMS Secure?
The security of SMS has always been a concern for industry, businesses and individuals alike since 1992, when the first message was sent. Now, over twenty years later, SMS has seen tremendous growth, with 7 billion SMS messages being sent in 2017. SMS is an integral part of our digital lives. We interact on a number of occasions from simple messaging, to appointment booking/reminder to transaction alerting and secure authentication. User authentication has been widely used for e-commerce from a user engagement of sending a temporary key or password to gain access, to more evolved systems such as Second Factor Authentication (2FA).
