WtsToolKit allows you to choose between using the Chrome browser or the built-in browser.

What is the difference between Chrome browser and built-in browser?

• The built-in browser defaults to Microsoft Edge, and by selecting this option, you can log in to multiple WhatsApp accounts simultaneously. For more details, please refer to Multi Account Feature Page.

• If you opt to use Chrome, you will be working in Google Chrome, and the multi-account feature in WtsToolkit will not be available.
