Panel, an open-source Python library for creating interactive data visualization applications, emphasizes the importance of secure authentication to protect data and ensure compliance. Descope, a no-/low-code customer identity and access management platform, simplifies this process by offering ready-to-use solutions for secure login, single sign-on (SSO), and user access control, leveraging OpenID Connect (OIDC) for scalable authentication. The tutorial guides users through integrating Descope into Panel applications, starting with basic authentication using magic links and social logins, and advancing to implementing SSO with Okta as the identity provider. SSO integration, particularly significant for B2B applications, streamlines user access, enhances security by relying on existing corporate credentials, and reduces the complexity of user management for developers. The tutorial also covers setting up role-based access control, authorization, token refresh mechanisms, and a logout feature, ensuring a seamless and secure user experience.
