I lost access to verification code


good afternoon. I did the factory reset on my phone and then restored the google account Duo to be able to access my facebook account because it has two factor authentication. it turns out that he is now asking for an activation key to be able to access the codes again. I do not have this activation key. what should I do? already tried to contact Facebook but they did not respond. help me. thank you



Hi there, you will need to work with Facebook support to regain access to your account. In the future, please make sure to create a Facebook recovery code for situations like this.
