I’ve had it several times, the app will ask for it every few months to confirm ownership.
FYI basic telematics is free for the first owner of a new car, but you have to pay £30 odd a year for the travel update that records your mpg for trips.
Also FYI, the second owner onwards will be paying £80 a year for basic plus travel!
I found this out when my telematics unit managed to delete itself and reset (supposed to be impossible unless you plug in a Honda dealer computer, but mine did it)
Luckily after a few days the dealer managed to convince Honda that I was the first owner and restore the remaining balance of my subscription.
