Answer 1 :
WhatsApp only allows one login per account in the world. Therefore, if you log in to WhatsApp from another device, it will immediately deactivate your WhatsApp account from the first device. Well, this is the fastest way to deactivate a WhatsApp account from the device.
If you have a SIM card with a registered mobile number, this will work quickly. Otherwise, please ask any SIM card supplier for a new SIM card. They will verify your details and provide you with a new SIM card with the same mobile number. This SIM card takes some time to activate.
However, if your phone is locked and no one knows the password, you can do this process patiently.
What if your phone is unlocked and anyone can access WhatsApp?

Finally, you can block the SIM card, get a new SIM card with the same number, install WhatsApp on other devices, and then deactivate it.
