Hi,
I'm sorry to hear about your mother's häçked account. It's definitely frustrating to deal with persistent häçkers. It's good that you were able to retrieve it using Gmail, but it's unfortunate that it got häçked again.
First, I would recommend securing your mother's Facebook account by following these steps:
1. Change the password: Make sure you use a strong, unique password that is not related to any personal information. Include a combination of uppercase and lowercase letters, numbers, and special characters.
2. Enable two-factor authentication (2FA): This adds an extra layer of security to your account. You can enable it by going to the "Settings" menu, selecting "Security and Login," and then turning on 2FA. This will require you to verify your identity using a code sent to your mobile number or email address whenever you log in from an unrecognized device.
3. Check connected apps and remove suspicious ones: Go to the "Settings" menu, select "Apps and Websites," and review the list of connected apps. Remove any apps that you don't recognize or aren't necessary.
4. Review active sessions: In the same "Security and Login" menu, you can view the list of devices and locations where your account is logged in. If you see any unfamiliar devices or locations, you can log them out or end the session.
Additionally, I would suggest contacting Facebook's support team for further assistance. They have a specific process to help users recover häçked accounts and can guide you through the necessary steps.
Remember to advise your mother to be cautious in the future by avoiding suspicious links, using strong passwords, and regularly updating her devices and software.
I hope this helps, and good luck in resolving the issue!
