At one point, Facebook forced its members to use their phone number for 2FA settings (control identity two factors). However, as of 2018, Facebook no longer requires a phone number, meaning that anyone can use the mode 2FA.
Two-factor authentication provides an extra level of security to your online accounts. In addition to the use of traditional code You need to provide another one that is usually sent via SMS or through an authentication application.
Το Facebook διαθέτει το χαρακτηριστικό 2FA εδώ και αρκετό καιρό. Ωστόσο, το κοινωνικό δίκτυο απαιτούσε να δώσετε τον τηλεφωνικό σας αριθμό κατά τη διαδικασία ρύθμισης. Ήταν απαραίτητο για να μπορεί το Facebook να στέλνει codeς ελέγχου ταυτότητας μέσω μηνυμάτων SMS.
However, providing a phone number to a social network that does not respect user data it is not the best.
Since 2018, however, the largest social network has simplified the two-factor authentication process, supporting third-party authentication applications, such as Google Authenticator and Duo Security.
To use 2FA without giving the social network your phone number, you'll need one account with an authentication application. Then all that's left to do is set up 2FA on Facebook using the authenticator app. See how…
