Second step: open the newly install WhatsApp and enter the desired number you want.
Third step: click on the 3 dots above at the upper right of your header, then open your settings shown on display.
Fourth step: open account, after opening it, select Two – step verification, once the Two – step verification is enabled. You’ll need to enter your PIN when registering your phone number with WhatsApp again.
