AuthenticatorResponse
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The AuthenticatorResponse
interface of the Web Authentication API is the base interface for interfaces that provide a cryptographic root of trust for a key pair. The child interfaces include information from the browser such as the challenge origin and either may be returned from PublicKeyCredential.response
.

Examples
Getting an AuthenticatorAssertionResponse
js
const options = {
challenge: new Uint8Array([
/* bytes sent from the server */
]),
};
navigator.credentials
.get({ publicKey: options })
.then((credentialInfoAssertion) => {
const assertionResponse = credentialInfoAssertion.response;
// send assertion response back to the server
// to proceed with the control of the credential
})
.catch((err) => console.error(err));
Getting an AuthenticatorAttestationResponse
js
const publicKey = {
challenge: new Uint8Array([
21, 31, 105 /* 29 more random bytes generated by the server */,
]),
rp: {
name: "Example CORP",
id: "login.example.com",
},
user: {
id: new Uint8Array(16),
name: "jdoe@example.com",
displayName: "John Doe",
},
pubKeyCredParams: [
{
type: "public-key",
alg: -7,
},
],
};
navigator.credentials
.create({ publicKey })
.then((newCredentialInfo) => {
const attestationResponse = newCredentialInfo.response;
})
.catch((err) => console.error(err));
