ID used on multiple devices

[cubabit]

We have been using biri on our website to assign an ID to a user before they contact our API to determine if they have accessed our service before.

We send the ID generated by biri (if it is supported in the client) to the API and it records the first usage of that ID with the user-agent supplied in the header.

We have found the same ID used by different devices - once from Chrome on a Samsung mobile, and then again on Safari on an iPhone. From what I understand of biri, the ID is unique to the device and this should not happen.

Am I misunderstanding something?

we also encountered this problem. the same ID on two different android devices.

Hmm. This is a problem. The ID from WebRTC may not be as unique as expected due to its length. Maybe combining Biri with more standard approaches will help solve this.
