Duo was released by Google alongside Allo, and unlike this application, Duo continues to work well. After reading the information about Duo's web assistance in recent weeks, the service is online. Just go to the Duo site and you can make calls from your browser.

No tedious setup to start with Duo on the web – no phone number authentication or QR code scanning like with other Google products. You just need to be signed in to your Google Account. Of course, you can choose to answer Duo calls on your phone instead of the web (you will receive a notification from the browser if you are logged in).

The page includes all your synchronized Duo contacts. You can click on a person in the list or search to start a call. The web version supports voice and video calls, and you get a preview window to make sure you look presentable before you start. The user interface can display regular or narrow video images (for a phone screen).

All the accounts we audited seem to have a Web Duo, which could be a broad deployment.
