Logging into Facebook can sometimes require an authentication code to verify your identity. This is usually sent via text message or email when Facebook detects a login attempt from a new device or location. However, if you have trouble receiving the code through these methods, Facebook does provide an Authentication Codes app that can generate login codes as well.
Why would I need an authentication code for Facebook?
Facebook may prompt you for an authentication code for the following reasons:
- You are logging into your account from a new device for the first time
- You are logging in from a new location or IP address
- It has been a while since you last logged in
- Facebook detects suspicious activity on your account
This is a security measure intended to verify your identity and prevent unauthorized access to your account. The code ties your login attempt to your specific account so Facebook can confirm it is really you trying to access your profile.
How does Facebook send authentication codes?
Typically, when Facebook prompts you for a login code, they will send it through either:
- Text message (SMS) – The code is sent as a text message to any phone numbers you have added to your Facebook account.
- Email – The code is emailed to any addresses associated with your account.
In most cases, users can simply retrieve the 6-digit code through text or email and enter it when prompted on Facebook to complete the login. However, there are some situations where you may be unable to access the code via text or email.
When you may need to use the authentication codes app
Some reasons you may need to use the app rather than text or email include:
- You no longer have access to the phone number or email associated with your Facebook account
- You have limited texts or emails available and don’t want to use one on the code
- You have concerns about the security of your texts or emails
- You are in an area with poor cell reception
- You do not have cell service or access to your inbox at the moment
In these types of situations, using the authentication codes app can provide an alternative method of obtaining your login code.
How to get and use Facebook’s Authentication Codes app
If you need to use the Authentication Codes app for Facebook, here is how to set it up and generate codes:
1. Download the Authentication Codes app
- On your mobile device, go to the Apple App Store or Google Play Store.
- Search for “Facebook Authentication Codes”.
- Download and install the official Facebook app.
2. Open the app and log in
- Open the Facebook Authentication Codes app.
- Enter your Facebook login email and password.
- Complete any additional prompts to verify your identity.
3. Generate authentication codes
- From the app’s main menu, tap “Generate Codes”.
- This will generate a list of one-time, 6-digit authentication codes.
- Tap any code to copy it, then paste into Facebook when prompted.
Once generated, each code will expire after a short time. However, you can simply generate additional codes as needed whenever you require a login authentication code for Facebook.
Tips for using the Facebook authentication code app
Here are some tips to make the most of the Authentication Codes app:
- Set up the app before you actually need a code – Don’t wait until you are locked out!
- Generate several codes at once for convenience.
- Note the expiration time for codes so you can refresh when needed.
- Make sure you are using the official Facebook app for security.
- Delete old codes once used or expired to avoid confusion.
- Keep your app login details secure, as anyone could generate codes.
Troubleshooting Facebook authentication codes
If you are having trouble with authentication codes from either the app or text/email methods, some things to try include:
- Double check that the code is entered correctly and has not expired.
- Try generating a new code on the app.
- Make sure your Facebook app or mobile OS is up-to-date.
- Check your mobile device’s internet connection.
- Restart your device and reopen the Facebook app.
- Clear the Facebook app’s cache and data before relogging in.
- Remove and re-add your phone number or email to your Facebook account.
If you still cannot obtain a code using either delivery method, you may need to contact Facebook customer support for additional help getting back into your account.
