# Why no new auth event when Apple Health reconnects?

**This is expected behaviour.** When you call `initConnection` for a mobile-native source like Apple Health, an [auth event](https://docs.tryterra.co/health-and-fitness-api/user-authentication/handling-authentication-events) is only produced if the device was not previously authenticated.

If it was already authenticated, the call is a no-op and the device keeps its original Terra `user_id`, which is why you see data payloads but no new auth event on reconnect.
