X two-factor authentication (2FA) – verification help (2024)

I lost my phone

• If you are enrolled intwo-factor authentication (2FA) and you generated a backup code, enter the backup code to access your account and update your Mobile settings.
• If you are no longer logged in to your account and do not have access to an active backup code, please contact our support team for assistance.

I bought a new phone

• We suggest backing up your old phone before you replace it. This will let you restore your app session on your new device, allowing you to continue to use two-factor authentication. (Note: If you're on X for iOS, we recommend you do an encrypted backup to preserve your app key. Typically, iCloud backups alone do not preserve the key and without an encrypted backup, you may be required to log back into your app using a temporary password generated on X.com)
• You can also unenroll fromtwo-factor authentication on your old phone, or from X.com if you have an existing open web session. If you do not have an open web session and you do not have your old phone, you can still log back in to X.com using your backup code.

• If you're logged in, verify that your phone is turned on correctly in your Mobile settings.
• If you recently changed your phone number or mobile carrier, you will need to update your settings. You may do so through the web, iOS, or Android apps if you are still logged in. If not, you may use a backup code to log in and change your settings. More information about backup codes is below.

I can't log in on my phone

• Adjusting your mobile settings may help with this issue. Log in to X.com from a desktop or laptop computer.
• Alternatively, try signing out of your account from the device you used to enroll in two-factor authentication. This will turn it off, and you can then sign back in with your username and password. Visit these articles for sign-out instructions: X for iOS or X for Android.

I get an error when I try to use my backup codes

• If you try to login using an inactive backup code, or try to use a backup code out of order, you will see an error message. You will need to generate a new backup code to log in.
• Your backup codes will only work when logging in to twitter.com, mobile.twitter.com, X for iOS or Android, or another X client. If you're trying to access a third party application associated with your X account, you'll need to use a temporary password instead of your backup code.
  

Using backup codes

A backup code is automatically generated for you when you turn on two-factor authentication through your iOS or Android X app. You can also generate a backup code on twitter.com. Write down, print or take a screenshot of this backup code. In the event that you lose your mobile device or change your phone number, you can use this backup code to log in to your account. Backup codes are not the same as temporary passwords.

To generate a new backup code through your X app:

1. Go to your Settings and privacy (on an iOS device, tap your profile icon; on an Android device, tap the navigation menu icon or your profile icon).
2. Tap Account, then tap Security.
3. Tap Backup code.
4. To use your backup code, log in to X with your usual username and password combination. When you see that atwo-factor authentication request has been sent, click the link to enter your backup code. Enter the backup code you've generated to log into the site.

I’m a Verizon customer and I can’t log in to my account

If you’re a new or existing Verizon customer, you may not be able to log in to your account because you’re not receiving atwo-factor authentication PIN via text messages. Try logging out of your X account and logging back in. You should then receive a verification PIN via SMS. If this doesn't resolve your issue, send a text message from your device with the message content, GO, to the X short code 40404. This will opt you in to receive SMS from X, which is consistent with your notification settings.
