- Afterwards, launch WhatsApp on your main device.
- Click on the application settings and select “ Connected devices »
- Select “ Add a device ”, then scan it QR code using your second device. WhatsApp can now be used without a phone number from your second phone. However, this option does not work only on a browser. Anyway, you also have the option of installing WhatsApp on a computer or Mac.
