How to use WhatsApp on Computer without any Software?

Use Whatsapp on Computer

To provide you with a richer communication experience, WhatsApp is now accessible both on your phone and your computer. WhatsApp Web is a computer based extension of the WhatsApp account on your phone. The messages you send and receive are fully synced between your phone and your computer, and you can see all messages on both devices. Any action you take on the phone will apply to WhatsApp Web and vice versa. At this time, WhatsApp Web is available only for Android, iPhone 8.1+, Windows Phone 8.0 and 8.1, Nokia S60, Nokia S40 EVO, BlackBerry and BlackBerry 10 smartphones.
WhatsApp Web is not another WhatsApp account. When you use WhatsApp on your computer and your phone, you are simply accessing the same account on these two devices.

You need to have an active WhatsApp account on your phone.
You need to have a stable internet connection on both your phone and your computer.
You need to use the latest version of Chrome, Firefox, Opera, Safari or Edge as your web browser on your computer.
