This trick will tell you how many devices have a WhatsApp account open
It is also possible to find out if a backup is being saved in another Gmail account
Sometimes there is a suspicion that someone is watching us, stealing private WhatsApp chats. Many times you will have a suspicion in your mind that WhatsApp account has been hacked. Almost all work in technology is possible. Often we forget to log out if we are using Gmail or WhatsApp web on the office system. This increases the risk of account hacking.

If you suspect that your WhatsApp account has been hacked it needs to be removed. We've come up with a trick to help you determine if your account has been hacked or your backup is being saved in someone else's Gmail. Let's start with this fun trick.

1. First open WhatsApp and click on the three dots at the top right.
2. Then click on WhatsApp Web Option.
3. The camera will be ready to scan the QR code if your account is not logged in to another system. (As shown in the photo below)
4. If WhatsApp is open or logged in to another system, it will not show the QR code first but will see the list of the system where your account is already logged in or open. Note: In this case click on Log Out from all devices.
5. Then go to Three Dots-> Settings-> Chat option again. There you will see the Chat Backup option below, click on it.
6. You will see the Google Accounts option. It should not contain any Gmail ID other than your account. If this happens remove it.

Note: This trick can be used to find out if a WhatsApp account is open in another system. Or whether the backup is being saved in another Gmail.
