Maybe we need a new way to connect Motrix to web browser

Is your feature request related to a problem? Please describe.
Now the extension we use to connect Motrix and browser need to input Key. But it is not working well when using multiple browsers, e.g. edge and chrome on one device, or edge on 2 devices.

Describe the solution you'd like
Considering FDM and IDM, is it possible to automatically connect Motrix without setting a key, or Motrix can save multiple Keys for different browsers/devices.
