Hello! I'm sorry to hear about your situation. It's important to act quickly to secure your father's Facebook account. Since you no longer have access to the primary email address and the häçker is receiving the OTP, you can try the following steps to regain control:
1. Recover the Yahoo Email: Try to recover the deactivated Yahoo email account. Sometimes inactive accounts can be reactivated by contacting Yahoo's support. This may involve providing personal information to prove ownership.
2. Contact Facebook Support: Explain the situation to Facebook Support. You can do this by going to the Facebook Help Center and looking for the "häçked Accounts" section. Facebook may ask you to provide proof of identity to verify your ownership of the account.
3. Report the häçked Account: You can report the häçked account to Facebook by using the "My Account is Compromised" option. This will prompt Facebook to investigate and take necessary actions.
4. Secure the Account: If you regain access, make sure to change the password immediately to something strong and unique. Enable two-factor authentication using an authenticator app instead of relying on email for OTP.
5. Update Security Settings: Review and update the security settings on the account, including checking for any suspicious activities, linked devices, or apps.
Remember to stay vigilant and regularly monitor the account for any unauthorized activities. It's also a good idea to educate your father on online security practices to prevent future häçks. Good luck, and I hope you are able to resolve this issue soon!
