AuthenticatorAssertionResponse extension type

The AuthenticatorAssertionResponse interface of the Web Authentication API contains a digital signature from the private key of a particular WebAuthn credential. The relying party's server can verify this signature to authenticate a user, for example when they sign in.

An AuthenticatorAssertionResponse object instance is available in the PublicKeyCredential.response property of a PublicKeyCredential object returned by a successful CredentialsContainer.get call.

This interface inherits from AuthenticatorResponse.

Note: This interface is restricted to top-level contexts. Use from within an iframe element will not have any effect.

Properties

authenticatorData → JSArrayBuffer

no setter
clientDataJSON → JSArrayBuffer
The clientDataJSON property of the AuthenticatorResponse interface stores a JSON string in an ArrayBuffer, representing the client data that was passed to CredentialsContainer.create or CredentialsContainer.get. This property is only accessed on one of the child objects of AuthenticatorResponse, specifically AuthenticatorAttestationResponse or AuthenticatorAssertionResponse.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
signature → JSArrayBuffer
The signature read-only property of the AuthenticatorAssertionResponse interface is an ArrayBuffer object which is the signature of the authenticator for both AuthenticatorAssertionResponse.authenticatorData and a SHA-256 hash of the client data (AuthenticatorResponse.clientDataJSON).
no setter
userHandle → JSArrayBuffer?
The userHandle read-only property of the AuthenticatorAssertionResponse interface is an ArrayBuffer object providing an opaque identifier for the given user. Such an identifier can be used by the relying party's server to link the user account with its corresponding credentials and other data.
