Every once in a while people ask how to run “two instances of Teams” on the same PC, both using a different account. This blog post will explain how you can do this using the Chromium-based version of Microsoft Edge and the Microsoft Teams Progressive Web App (PWA).

Step 2. Install Microsoft Teams as a Standalone App
Once a new profile is created, you can visit the Microsoft Teams web app. If you’re asked to sign in, please use the account you would like to use in Teams (and likely used to sign-in to the Edge profile). You may be prompted to download the Teams desktop client, if so, please select the “Use the web app instead” option as shown below.
After the Teams web app loads, you can go into your browser menu (represented by three horizontal dots) and select the option to install the web app:
Once the app is installed you can use it like any other application. You can even run multiple instances of the Teams progressive web app.
