### Authentication Expiry

The host app is expected to monitor [MoveAuthState](https://docs.movesdk.com/move-platform/sdk/models/moveauthstate) updates via`authStateUpdateListener`API and handle those changes accordingly.

Check [Authentication updates and expiry](https://docs.movesdk.com/move-platform/sdk/moveauthstate#authentication-updates-and-expiry) for more details.&#x20;
