I got a response from TeslaFi and Stats App saying they're good-to-go. I also use A Better Routeplanner heavily and posted an inquiry in their forum but haven't seen a response as yet. I haven't tried logout out of anything but the Tesla app itself to see what happens.
EDIT: and in case it wasn't obvious, I use TeslaFi heavily also, and use the Stats App too, but not that often.
do you generate your own token for teslafi or login to let it generate one for you? What I am curious about is what happens when someone attempts to login to one of these "non tesla" apps, and whether it will trigger the 2FA, or what. Its more curiosity on my end since I dont use them, but I suspect that many that will turn this on, will, so thats the reason I was asking.
