Examples
Getting an AuthenticatorAssertionResponse
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
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: "msanchez@example.com", displayName: "Maria Sanchez", }, pubKeyCredParams: [ { type: "public-key", alg: -7, }, ],};navigator.credentials .create({ publicKey }) .then((newCredentialInfo) => { const attestationResponse = newCredentialInfo.response; }) .catch((err) => console.error(err));Specifications
