First, users need to understand What is Facebook Code Generator? A Facebook code generator is a security feature present in the Facebook application. It is used to coordinate with two-factor authentication. After two-factor authentication, users will get a unique security code from their devices to verify an individual.
It is enormously advised users enable the two-factor authentication feature. Because if the users are logging in from anyone’s device or from another location, then Facebook will ask for a security code to log in which ensures the security of its users. If users are not interested to enable the same for their account, then an individual just needs their username or email address and password to log in to the Facebook application which sometimes can be risky because it increased the chances of hacking one's profile by others.
Users can access the confirmation code in three different ways mentioned below:
Facebook texts Confirmation Code: If users planned to change their contact number, Facebook can text users an authentication or verification code only on the linked contact number with their account. From the login code page select Need another way to authenticate? then click on Text me a Login code and wait until the text will appear on the screen. Users can also let Facebook call them.
Use Saved Recovery Codes: Users got a chance to save several recovery codes as a backup after setting up Two-Factor Authentication. Users are guided to save recovery codes as soon as they get access to their accounts. If ever, users lost their access to the code generator they can use one of the recovery codes to log in to the Facebook application from anywhere or from any device.
Approve Log In from an Authorized Device: After successfully logging in, Facebook asks their users to remember it or not. In this scenario, users don’t need a login code to access Facebook. Check if you’re still logged in on any of the devices. When you found a device, where users are still enabled to access Facebook, a notification will be reflected to approve the new login.
However, a code generator is the most effective and convenient way to access Two-Factor Authentication without the contact number. Also, the code generator is available in the Facebook application itself for iOS and Android users.
