BN Cloud login without making new device

[GeorgeYellow]

Would anyone else using the public Protocol Buffer API happen to know:

1. An endpoint for Account login without the model, serial number tuple?
2. What the device limit is?
3. What endpoint to list and remove devices?

I can use GetAuthRequestV1 to login (assuming a serial number), but I still need to use another endpoint to get the remaining information.

While Android allows preservation of device information, IOS doesn't allow saving a constant serial number. Has anyone looked at how the IOS app manages?
