We have a new use case where we would have an app running on our customers' devices, but we cannot ask them to login. I was thinking that I can give each of these devices an access key that it can use to authenticate with our cloud service. But I see that there is limit of m2m key exchanges of only 50000. With 10 min session token expiry, it means ~4000 exchanges for a single device. This means only 12 devices are possible. I can increase session time to lets say, 100 minutes, increasing the numbers to ~120 devices, but still not enough. Can anyone suggest an alternative? We know we can create per device based user, but still does anyone have any good alternatives.

Hey Ritik, Sachin opened a ticket about this. Kevin replied yesterday evening on this topic. Let us know if you have any follow up questions from that.
