Can't Get Facebook Account Back Because Two Factor Authentication
If you can't access Facebook without a confirmation or reset code, there's hope! Facebook's Code Generator is only one of many layers of Facebook security.
We'll show you how to log into your account using alternative methods to receiving a Facebook confirmation code.
Why Do You Need a Facebook Confirmation Code?
Once you enable Facebook's two-factor authentication, which we strongly recommend, Facebook will ask you for a security or confirmation code to log in from a new location or device. To find out more about two-factor authentication and why you should use it, read our guide explaining the security method.
Without two-factor authentication, you only need your username or email address and password to log into your Facebook account.
By enabling Facebook's two-factor authentication, you've added an extra layer of security.
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.
How to Set Up Facebook's Two-Factor Authentication
To enable two-factor authentication, open Facebook in your browser, click the arrowhead in the top right to expand the navigation menu, and go to Settings & Privacy > Settings > Security and Login. Under Two-Factor Authentication, click Edit next to Use two-factor authentication. At this point, you might have to enter your password.
To enable two-factor authentication, select the method you'd like to use for Facebook's verification. You can either proceed with anAuthentication App (recommended), Text Message (SMS), or a Security Key. Make your selection and click Next.
We went with the Text Message option and entered the six-digit code Facebook texted to our mobile number. You can use a phone number already associated with your account or add a new one. Once you've entered the Facebook confirmation code, click Finish to complete the initial setup.
Now you can add an authentication app, save recovery codes, and create a security key; click Setup next to the respective method. You can also change the phone number that Facebook uses to text you a login code; just click Manage next to the Text Message (SMS) option.
Note: If the code from your Google Authenticator app won't work while you're setting is up as your 2FA method, open the Authenticator app, tap the three-dot icon in the top right, and selectSettings > Time correction for codes. Now it should work.
If you need to temporarily disable two-factor authentication, just click Turn Off on Facebook's 2FA settings page, and you'll be able to log in using your basic login credentials.
How to Access the Facebook Code Generator
Code Generator is a convenient way to access two-factor authentication codes without a mobile number. The tool will come in handy when you're traveling or don't have mobile reception. Code Generator is available inside the Facebook app for iOS and Android.
To access the Facebook Code Generator from Android or iOS, open the Facebook app, click the hamburger icon in the top right, scroll down, expand the Settings & Privacy menu, and select Code Generator. Here you'll see the tool run through new security codes every 30 or 60 seconds.
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 to an event where you lose access to the Code Generator.
1. Let Facebook Text You a Confirmation Code
Do you still have access to the mobile phone number you defined under two-factor authentication? 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.
2. Use a Saved Recovery Codes
After setting up two-factor authentication, you had the chance to save a set of recovery codes as a backup. Maybe you printed the code, took a screenshot, or wrote it down and stored it in a safe location.
If you haven't saved recovery codes, be sure to do it as soon as you regain access to your account. Should you ever again lose access to Code Generator, you can use one of these codes to log into Facebook from a new device or location.
3. Approve the Login From an Authorized Device
Whenever you successfully log into Facebook from a new device, application, or browser, Facebook asks you whether you would like to remember it. You won't need a login code the next time you want to access Facebook from that authorized device and location. Now that you can't access Code Generator, this could be your private backdoor into your Facebook account.
Try to access Facebook from a browser or app you've used previously. Maybe you're still logged in on an old laptop, your work computer, or your tablet. When you find a device where you can still access Facebook, you should see a notification asking you to approve the new login.
4. Confirm Your Identity
None of this worked? Submit a request to Facebook. In the menu that pops up after you select Need another way to authenticate (see option 1), select Get More Help, and let Facebook walk you through the steps to recover your account.
You'll have to enter an email address and upload a copy of your ID, which can be a passport, driver's license, national ID card, or one of many more official documents.
Once you have provided the requested information, Facebook will email you with further steps for account recovery.
Did you manage to log back into Facebook? Remember to save recovery codes, set up a new authentication app, and update your other recovery options.
Did You Lose Your Mobile Device?
To prevent access to your Facebook account from a lost phone or laptop, in case you didn't log out of the app, terminate the app's Facebook session. If you registered your phone's number, go to Facebook > Settings & Privacy > Settings > Mobile > Lost your phone? and click the Log Out on Phone button.
At this point, you should Remove the number of the lost phone.
If you have lost a device other than your phone, of if haven't set up your mobile number, there are multiple ways to log out of Facebook from other devices.
Go to Facebook (on a recognized device) > Settings & Security > Settings > Security and Login > Where You're Logged In, find the respective session, andLog Out. If in doubt, end multiple sessions. This will log you out of the app.
Until you get your phone back or can set up Code Generator on a new phone, you can save a batch of backup codes as described above. You could also set up another third-party app to generate codes.
And in the future, always make sure at least one device, other than your laptop or phone, has an authorized login. It could be a home computer that you'll always have access to. Only ever let Facebook remember devices and locations that are private and safe. And frequently review your list of Authorized Logins and Remove outdated items.
To be safe, also update your Facebook password.
Keep Your Facebook Account Safe
Every day, we hear from people who have lost access to their Facebook account. Unfortunately, we can't help most of them because they failed to set up safety options, had their passwords cracked, and the hackers changed their password and recovery options. In cases like that, you can only hope that Facebook will help you recover your account.
So, don't let it get that far. It only takes a few minutes to enable two-factor authentication and save Facebook recovery codes. Once disaster strikes again, you will be able to recover your Facebook account.
