I have a web application using .NET Identity which is using the standard (cookie based) authentication.

I have a separate controller for a mobile app that uses JWT authentication.

Both of these are set up to be used in the middleware and all works fine.

Whet I would like to be able to do is, from the mobile app, open a particular page in the webapp in the device web browser to a defined URL with a ?token={token} type of parameter and Identify the User so I can perform the standard user manager Sign In.

But I can’t work out how to identify the user from the JWT as a browser string parameter.

Any ideas?
