Are push tokens unique to the device or user profile?

Push tokens are unique identifiers generated by the device for the purpose of receiving push notifications. Each device registers with the push notification service and is assigned a distinct push token. This token allows the system to send notifications specifically to that device, ensuring that messages reach the correct destination.

When considering user profiles, it's important to note that a single user may use multiple devices, each having its own unique push token. Thus, while a user can interact with the system across different devices, the push tokens themselves are tied to individual devices rather than to the user profile as a whole. This distinction is crucial for understanding how notifications are routed and delivered within the app framework, emphasizing the device-centric approach of push token assignment.
