The id
read-only property of the
PublicKeyCredential
interface is a DOMString
, inherited
from Credential
, which represents the identifier of the current
PublicKeyCredential
instance.
This property is a base64url
encoded version of PublicKeyCredential.rawId
.
Note: This property may only be used in top-level contexts and will
not be available in an <iframe>
for example.
Syntax

Value
A DOMString
being the base64url
encoded version of PublicKeyCredential.rawId
.

.then(function (newCredentialInfo) {
var id = newCredentialInfo.id;
// Do something with the id
