Whatsapp is one of the most popular instant messaging apps across countries in the world. The Facebook-owned platform has more than Two billion users and offers end-to-end chatting experience.

However, hackers only need a phone registered with a Whatsapp account to dupe users into a variety of scams including sharing their verification code to gain complete access to an account, impersonating a contact, links to malicious software, phishing attempt and more. Even if you are using an official Whatsapp Messenger or mods like Yo Whatsapp, you have to keep a vigilance over it's unauthorized access.

The following are things you should do immediately, if your Whatsapp Account get hacked.

Step 1: Alert your Family and Friends that your Whatsapp Account has been hacked and they might receive objectionable text or content from the compromised account. Also, update your status on all social platforms including Instagram, Facebook and Twitter that your Whatsapp Account has been hacked.

Step 2: Remove and Delete your Whatsapp Messenger Account to stop further unratified use of it. Many of the users misunderstand uninstalling of an App same as deleting it, but that's not the case. Uninstalling of Whatsapp won't deactivate your account. You must delete your account right from the app itself or go to web support if needed. Once you deactivate your account, your message history and goggle drive backup would be erased. Moreover, you 'll be auto removed from all Whatsapp groups.

             OR

Another way to deactivate your Whatsapp Account is to send an email to "[email protected]" with the title "Lost/Stolen: Please Deactivate my Account". After Deactivation, you have 30days to recover your account.

Step 3: Make sure you check whatsapp web. Whatsapp web is the extension of the Whatsapp Messenger used to synchronize your phone with your computer. When hacked, Log on to your PC and click on the option, "Log out from all Computers".

Finally, Here is what to do to recover your Whatsapp Account. 

In order to get back your Whatsapp Account, you need to re-install Whatsapp on your device with your phone number. Immediately that is done, you will receive a Six-digit verification code that Whatsapp reads and logs you in automatically. Once you log in, the hacker will be automatically logged out of your Account. 

But if the hacker has re-activates the two steps verification after gaining access to your Whatsapp Account, you will have to wait for seven days to recover your Account. I hope this would be of help to someone.
