Yes, you can. Open the 2FAS extension settings (Right-click on the 2FAS browser extension icon and choose “Options”), go to the “Settings” tab, and click “Add new device.” Now simply scan the QR code visible on the PC/Mac screen with another device. To do that, open the 2FAS app, go to Settings, Browser Extension, and tap the “PAIR WITH WEB BROWSER”/”+ ADD NEW” button, depends if you’ve already paired another browser before.
