Why Facebook's Two-Step Authentication Puts Your Privacy In Check

Everything that surrounds Facebook is surrounded by controversy. After a reputation crisis such as Cambridge Analytica, the controversies over the use of private data of users for commercial purposes or the resignations of important managers, today we are talking about the 2FA.

One of the latest controversies arising around the platform has to do with a service created in principle to increase the safety of users: two-step authentication, or 2FA.

As most users know, the authentication system serves to secure the account in the face of hacking attempts or access to it by strangers. Through a series of steps it is ensured that only its authentic user can access it. However, the authentication steps requested by Facebook can also serve to attack privacy.

The request for the phone number that is made by default is used to associate the number with the user, to relate it to the phone books of friends who have Facebook installed on their mobile phone, as well as their hobbies or trends, and to cross data with other platforms of the company. (Instagram or WhatsApp) or the applications with which Facebook has an agreement to exchange information.

Although it is a method that is not usually requested to users who lack pages or businesses, the phone number is a piece of information left in the hands of Facebook and that you can use for the purpose you want.

It has been announced for some time that Mark Zuckerberg is considering merging Messenger, Instagram and WhatsApp chats. In this way you could exchange the data you get from these three social networks, each one the most used in your area, with greater ease and weave a very complicated network to dodge for any user.

Many are the controversies that surround Facebook and it seems that every day loses the trust of more users. If adding new measures to protect accounts is a desirable practice, there remains the feeling that any change means a loss of privacy more.
