All of you who have been on the ball and enabled two factor authentication on your Facebook account are about to get really annoyed. Some researchers have discovered that the same phone number you gave Facebook to secure your account, is being used to target you with advertising.
When Facebook were called out on the practice, they defended it by suggesting users could simply turn off two factor authentication and opt out of the data sharing. I know what you are thinking. You shouldn’t have to choose between privacy and security. Fortunately, there is a better solution. In May they released a feature called Code Generator. It allows you to use two factor authentication without using your phone number.
If you are currently using your phone number for two factor authentication on your Facebook account and don’t want it used for targeting adds, I suggest you switch to the Code Generator. The added bonus, it works even if you don’t have text messaging or an Internet connection available.
