Suddenly received facebook verification code

This situation may be that your friend lost his password, set up a "trusted contact person" and chose 3 to 5 friends including you who can easily contact by email or phone. Once he cannot log in to the account, Facebook will provide a set of verification codes to a group of trusted contacts to help retrieve the account.

pay attention to

1. Please confirm whether your friend's account has been stolen. Try to verify their requirements through different channels and confirm whether the account has been stolen.
