ngrok offers native integrations with authentication solutions like Auth0, providing a complete authentication solution that makes both end-users and security happy. To integrate ngrok with Auth0, users need to sign up for free accounts with both services, install the ngrok agent, and configure the Auth0 application settings. Once integrated, users can leverage additional features such as passwordless auth, self-service account recovery, URL-based authorization, monitoring live sessions, and auditing traffic through the ngrok dashboard and integrations with observability systems like AWS and Datadog Logs. With this setup, users can deliver a production-grade solution that provides end-users with a smooth sign-up experience and security features such as audit trails and session management.
