Summary

Public constructors
`GetRestoreCredentialOption(@NonNull String requestJson)`

Public methods
`final @NonNull String`	`getRequestJson()` the request in JSON format in the standard webauthn web json (https://w3c.github.io/webauthn/#dictdef-publickeycredentialrequestoptionsjson).

Inherited methods

From androidx.credentials.CredentialOption

`final @NonNull Set<@NonNull ComponentName>`	`getAllowedProviders()` a set of provider service `ComponentName` allowed to receive this option (Note: a `SecurityException` will be thrown if it is set as non-empty but your app does not have android.permission.CREDENTIAL_MANAGER_SET_ALLOWED_PROVIDERS; empty means every provider is eligible; for API level < 34, this property will not take effect and you should control the allowed provider via library dependencies)
`final @NonNull Bundle`	`getCandidateQueryData()` the partial request data in the `Bundle` format that will be sent to the provider during the initial candidate query stage, which will not contain sensitive user information
`final @NonNull Bundle`	`getRequestData()` the request data in the `Bundle` format
`final @NonNull String`	`getType()` the credential type determined by the credential-type-specific subclass (e.g. the type for `GetPasswordOption` is `PasswordCredential.TYPE_PASSWORD_CREDENTIAL` and for `GetPublicKeyCredentialOption` is `PublicKeyCredential.TYPE_PUBLIC_KEY_CREDENTIAL`)
`final int`	`getTypePriorityHint()` sets the priority of this entry, which defines how it appears in the credential selector, with less precedence than account ordering but more precedence than last used time; see `PriorityHints` for more information
`final boolean`	`isAutoSelectAllowed()` whether a credential entry will be automatically chosen if it is the only one available option
`final boolean`	`isSystemProviderRequired()` true if must only be fulfilled by a system provider and false otherwise

Public constructors

GetRestoreCredentialOption

Added in 1.5.0-beta01

public GetRestoreCredentialOption(@NonNull String requestJson)

Public methods

getRequestJson

Added in 1.5.0-beta01

public final @NonNull String getRequestJson()

the request in JSON format in the standard webauthn web json (https://w3c.github.io/webauthn/#dictdef-publickeycredentialrequestoptionsjson).

Note that the userVerification field of the requestJson will always be overridden to discouraged to support passive authentication during restore flow.

GetRestoreCredentialOption cannot be requested with other credential options because of conflicting user experience. When requesting restore credential, only a single GetRestoreCredentialOption must be supplied.
