I am following the instruction to setup device flow authentication: Call Your API Using the Device Authorization Flow.
It works fine based on the steps in the doc. But it uses browser to open the verification_uri_complete received from /oauth/device/code post response.
My use case is to let the user scan a QR code which will open an app on their mobile. The app is built by me. The app is already authenticated with the user’s credential via using the auth0 sdk. So the app has got the access token and refresh token. How can I use the existing token from the app to authenticate the device flow? I don’t want the user to login again if he already logged in to the app.
