Nowadays, the continuous development of technology, in addition to the benefits and conveniences it offers in various areas of everyday life, poses risks to the security systems of both people and organizations and businesses. In order to address the risks and threats in matters related to the security of personal data, there are certain measures that must be taken. In particular, one way to maintain security standards is 2-step verification (an additional security measure, with which users combine two different identification elements), also known as 2 Factor Authentication. The activation and implementation of 2-step authentication has evolved into an essential security agreement in order to secure and facilitate online services and other important transactions, such as access to accounts, password change / reset, electronic payments, financial transactions and more. In addition, this security method verifies the user's identity and protects the system from phishing or hacking. So, when 2 Factor Authentication is enabled, a hacker needs more personal information from users, not just their password, to gain access to their account. At the same time, users receive a notification message that someone else is trying to access their account. In 2-step verification, users are asked to add and save an additional piece of information to verify their identity. There are many forms for implementing 2FA, the most common being SMS.
Regarding 2 Factor Authentication via SMS, it is perhaps the most widespread method, as it is easy and convenient for the user, since everyone has a mobile phone and always has it with them, thus making the verification process more immediate and faster. Furthermore, passwords generated by an SMS provide an additional layer of security, so that even if someone has the user's username and password, they still cannot access their account unless they have access to their SMS.
Among the properties of 2-step verification is the assurance that even if one of the elements (username and password) is compromised, the other element (a code valid for a specific period of time) prevents hackers from breaking into an account , thus reducing the risk of data theft.
Therefore, 2 Factor Authentication via SMS has a number of advantages , including its easy and user-friendly implementation, enhanced security, reduced risk of theft of personal data and information, as well as reduced operational and security costs. Finally, it ensures that every user can benefit from this security feature even with a simple phone , regardless of mobile data
