    <p>The <code>hmac-secret</code> extension provides two PRFs per credential: one which is used for requests where <a data-link-type="dfn" href="#user-verification" id="ref-for-user-verification⑤②">user verification</a> is performed and another for all other requests. This extension only exposes a single PRF per credential and, when implementing on top of <code>hmac-secret</code>, that PRF MUST be the one used for when <a data-link-type="dfn" href="#user-verification" id="ref-for-user-verification⑤③">user verification</a> is performed.
