Now, to check out whether you can make calls through your browser via Duo, first launch the application and then select “More” and choose Settings. After this, select Add Account and key in your Google account credentials.
Once you have accomplished the above, click here to navigate to the official Google Duo custom portal and enter your phone number along with selecting geographical details.
