I don't know if anyone noticed, but the browser based mytesla now uses a site called auth.tesla.com and OpenIDConnect/OAuthV2 to authenticate you. Earlier this used to be simple OAuthv2 at my.teslamotors.com/user/login Why would Tesla externalize authentication to a separate auth provider? The only reasonable explanation is to reuse "Tesla identity" beyond the two services it officially offers - the Tesla app, and the Tesla website. Are they planning on opening some of the API or identity to third party apps? I'm betting they are. And this would be a heckuva cool value-add to Tesla at a very low cost. Something they should have done a VERY long time ago. When? Is anyone's guess.
