IMPORTANT: In July 2025, we stopped releasing new versions of KTX modules, and we removed the KTX libraries from the Firebase Android BoM (v34.0.0). If you use KTX APIs from the previously released KTX modules, we recommend that you migrate your app to use KTX APIs from the main modules instead. For details, see the FAQ about this initiative.

AppCheckToken

abstract class AppCheckToken

Class to hold tokens emitted by the Firebase App Check service which are minted upon a successful application verification. These tokens are the federated output of a verification flow, the structure of which is independent of the mechanism by which the application was verified.

Summary

Public constructors
`AppCheckToken()`

Public functions
`abstract Long`	`getExpireTimeMillis()` Returns the time at which the token will expire in milliseconds since epoch.
`abstract String`	`getToken()` Returns the raw JWT attesting to this application’s identity.

Extension functions
`operator String`	`AppCheckToken.component1()` Destructuring declaration for `AppCheckToken` to provide token.
`operator Long`	`AppCheckToken.component2()` Destructuring declaration for `AppCheckToken` to provide expireTimeMillis.
