2FA, or Two Factor Authentication, is a security measure to help you protect your account. The process requires you to use your phone number to get a secret code to enter into Facebook to gain access to your account. It seems Facebook, though, thinks that 2FA is used for other things. According to Tech Crunch,
Interesting statement considering Facebook only added a non-2FA process a few months ago.
Facebook, once again, misuses the information we provide for its own gain.
What you can do
You can let Facebook know that you do not appreciate its breach of trust and misuse of your information. How? Well, you can close and delete your Facebook account. I know, this is not practical. Another way to send a message about your dissatisfaction is to use the Mozilla Foundation’s online petition to let Facebook know you object to their practices.
Please share this information with others if you believe that Facebook is wrong in its practices of using your personal information.
