Android P FingerprintManager.hasEnrolledFingerprints replacement : <p>As of <strong>Android P (API 28)</strong> the <code>FingerprintManager</code> API was deprecated and Google suggests we should switch to <code>BiometricPrompt</code> API.</p>

<p>However <code>FingerprintManager</code> has a method named <code>hasEnrolledFingerprints</code> that we're currently using to display a prompt to the user right after he logs in with email / password where we ask him if he wants to use his fingerprint for future authentication (such as when the session expires).</p>

<p><code>BiometricPrompt</code> API doesn't have a similar method, so this breaks our current UX and we're not sure how to address this.</p>

<p>I guess the alternative would be to simply encrypt the user's password without allowing him the option to manually "enroll", and simply use the <code>BiometricPrompt</code> API when his session expires, but we feel that the user should be informed and opt-in into this feature.</p>

<p>I did some digging trying to find out where I could ask such a question on Google's  feedback platform, but couldn't find where.</p>

<p>Any suggestions on this would be appreciated.</p>
