     <p>Auth0 by Okta provides a simple and customizable login page to authenticate your users. You can dynamically add new capabilities to it - including social login, multi-factor authentication, or passkeys - without making changes to your app’s code.</p>
     <p>We help protect your app and your users from attacks - defending your application from bot attacks and detecting runtime anomalies based on suspicious IPs, breached credentials, user context, and more.</p>
