Hello friends today I am discussing a video topic for you. Today's video topic is about WhatsApp security update. If you keep this setting on in your WhatsApp account, you will be notified with a message when someone tries to login to your WhatsApp account on another phone. If it's not your device you don't accept. And if you log in on your other device, you can accept. If you turn on this security notification, your WhatsApp won't be able to login to any other phone.
