Ford App with Multiple Cars

I have an old F150 and a new Mustang Mach-E, both in the Ford App on my phone.
Be default the Tronity app is only picking up the F150, so it is not working.
Customer support is assisting with tying my Tronity app to my Mustang, but the app should be smart enough to see that there are multiple cars in the Ford app and allow me to pick the correct one.  Additionally for security purposes the Tronity app should NOT require my Ford App username and password as this is a HORRIBLE practice.  There should be a delegation of privledges to an API token or something along those lines rather than just giving Tronity the user's credentials to an external site!
