What is the role of device tokens in the context of push notifications?
- Authentication codes for notification servers
- Encryption keys for securing notifications
- Memory addresses of notification data
- Unique identifiers assigned to mobile devices
Device tokens serve as unique identifiers assigned to mobile devices in the context of push notifications. When a mobile app registers for push notifications, the server generates a unique token for the device. This token is used by the push notification service to route notifications to the correct device. It ensures that notifications are delivered to the intended recipient and aids in maintaining user privacy by associating notifications with specific devices rather than personal information. Understanding the role of device tokens is essential for effective push notification implementation.
