Step by step

    Try alternative verification methods

    On the Facebook login screen, enter your email and password. When prompted for the 6-digit code, click 'Having trouble?' below the code field. Select 'Use one of your saved backup codes' if you previously saved them, or choose 'Get codes via SMS' to try receiving codes on a different phone number.

    Note: Facebook allows up to 5 phone numbers for backup SMS delivery. Add multiple numbers in Security Settings before issues occur.

    Use your saved backup codes

    If you previously downloaded backup codes, locate the file on your device or printed copy. Enter any unused 8-digit backup code in the verification field. Each code works only once, so mark it as used after successful login.

    Note: Backup codes are typically saved as 'facebook_backup_codes.txt' in your Downloads folder when first generated.

    Access through a recognized device

    Try logging in from a device you've used before, such as your home computer or tablet. Facebook may recognize the device and allow login without two-factor authentication. Look for the option 'Don't ask for codes on this device' during previous logins.

    Note: Clear browser cache first, then try private/incognito mode if the recognized device method doesn't work initially.

    Contact trusted friends for help

    Click 'No longer have access to these?' on the verification screen. Select 'Contact friends' and choose 3-5 trusted friends from the list. Facebook will send each friend a security code. Collect these codes from your friends and enter them to regain access.

    Note: This method requires friends who actively use Facebook and can respond quickly. Set up trusted contacts in advance through Security Settings.

    Submit an identity verification request

    If other methods fail, click 'Get help from Facebook' on the login screen. Submit a government-issued photo ID that matches your Facebook name. Upload a clear image showing your full name and photo. Facebook reviews requests within 24-48 hours.

    Note: Use passport, driver's license, or national ID. Ensure the name exactly matches your Facebook profile name for faster approval.

    Reset two-factor authentication settings

    Once you regain access, immediately go to Settings & Privacy > Security and Login > Two-Factor Authentication. Turn off the current method, then re-enable it with a working phone number or authentication app. Download new backup codes and store them securely.

    Note: Consider using an authentication app like Google Authenticator or Authy instead of SMS for better security and reliability.
