Where Can You Find a Facebook Confirmation Code?
You can obtain a Facebook login code in three different ways:
- Facebook can text a confirmation code to a mobile number associated with your account.
- From an authentication app, like Duo or Google Authenticator. Moreover, the Facebook mobile app includes a Code Generator that automatically generates a fresh security code every 30 or 60 seconds.
- From a list of Facebook recovery codes that you have saved as a backup.
Beyond codes, you can also create a physical second-factor security key to log into Facebook through USB or NFC.
Since two of the methods above depend on a mobile device, make sure you have at least one other method to log back into Facebook, in case you lose that device.
Lost Your Phone and Can't Use Code Generator?
When you've set up your phone to be the key to your Facebook account, losing or breaking it could be a problem. Here's what you can do in the event that you lose access to Code Generator.
1. Let Facebook Text You a Confirmation Code
Do you still have access to the mobile phone number you included under two-factor authentication? Maybe your provider could send you a new SIM with the same number. In that case, let Facebook text you a confirmation code. Unfortunately, Facebook can only use that one number for two-factor authentication, even if you've set up other phone numbers under your profile.
From the screen asking you for the login code, select
Need another way to authenticate? (bottom left), then click
Text me a login code, and wait for the text to come in. You can also let Facebook call you.
