### Authentication Expiry

The host app is expected to monitor [MoveAuthState](/move-platform/move-sdk-1.x/sdk/models/moveauthstate.md) updates via`authStateChangeListener`(Android / [iOS](/move-platform/move-sdk-1.x/sdk/api-interface/ios/services.md#set-sdk-auth-state-listener)) API and handle those changes accordingly.

Check [Authentication updates and expiry](/move-platform/move-sdk-1.x/sdk/models/moveauthstate.md#authentication-updates-and-expiry) for more details.
