Logging In to Facebook on a New Phone: Approvals and Codes

On a new phone, Facebook may ask you to approve the login from another device or enter a code. Keep the old phone signed in until the new one works.

What to expect

Facebook watches for sign-ins from devices it has not seen. On a new phone you may see a request to approve the login from a device where you are already signed in, a code by text or email, or a code from your authenticator app if two-factor is on.

Approve from another device

1. On the new phone, sign in with your email or number and password.
2. On your old phone or computer, open Facebook and look for a notification asking if it was you.
3. Tap Yes or Approve.
4. The new phone signs in.

If no notification appears, choose Try another way on the new phone.

Codes

Move your authenticator first

If you use Google Authenticator, Microsoft Authenticator or similar, transfer the codes to the new phone while the old one still works. If the old phone is gone and you have no recovery codes, you will need Facebook's identity steps.

Changed your number too?

Update the number in Accounts Center before switching SIMs. See changing your number on Facebook.

Login fails repeatedly

• Sign in on Wi-Fi you have used before.
• Turn off VPNs.
• Wait a few hours after several failed tries.
• Use Forgotten password instead of guessing.

Messenger and Instagram

Messenger uses your Facebook login. Instagram has its own login, but if the accounts are linked in Accounts Center, a single approval may cover both.

Saved logins

Facebook can remember your login on a device so you can tap your profile picture instead of typing a password. Remove saved logins from phones you sell or give away, in the Security and login settings.
