Start automatically without unlock prompt

Is it possible to start the desktop application automatically on login, without having it to prompt to unlock?

Now when biometrics is supported in the browser add-on, which is a great feature, it needs the desktop application to be running in the background. Therefore, I have set the desktop application to start automatically when I login, but it would be nice if it doesn’t prompt to unlock, until I actually need to login somewhere.

I’m using Firefox on Windows 10.
