How to prevent my WhatsApp account from a hacker? Someone has access to my WhatsApp account. How can I block this?

To prevent your WhatsApp account from being hacked, you should take the following steps:

1. Use a strong password for your WhatsApp account, and do not share it with anyone.
2. Enable two-factor authentication for your WhatsApp account. This will require an additional code to be entered when logging in from a new device.
3. Be wary of suspicious links or messages you receive through WhatsApp, and do not click on any links or download files from untrusted sources.
4. Keep your device software and WhatsApp app updated to ensure that any security vulnerabilities are patched.
5. If you suspect someone has unauthorized access to your WhatsApp account, change your password immediately and contact WhatsApp support for assistance.
6. Check your WhatsApp Web Sessions and log out of all other active sessions if you find any suspicious.
7. Keep your phone and WhatsApp account backed up so that you can restore your data and contacts if your account is compromised.
8. Do not share your personal details like phone number, email id, OTP, or QR Code with any unknown person.
