RestoreCredential

Artifact: androidx.credentials:credentials

Kotlin |Java

public final class RestoreCredential extends Credential

java.lang.Object
↳	androidx.credentials.Credential
	↳	androidx.credentials.RestoreCredential

Represents the user's restore credential for the app sign in. The restore credential is used to restore the user's credential from the previous device to a new Android device.

By creating a RestoreCredential for the user, the credential will be automatically transferred over to the user's new device if the user selects the app to be transferred from the old device during the setup stage.

The RestoreCredential can only be used for apps that the users have selected to be restored. The RestoreCredential for all other apps will not be transferred over from the old device. This Credential can be used to create a seamless authentication user experience by providing a 0-tap sign-in experience. If the RestoreCredential is available for an app, the user can be signed in programmatically without the user's input.

Throws
`kotlin.IllegalArgumentException`	If `authenticationResponseJson` is empty, or if it is not a valid JSON
