Dash, a low-code framework by Plotly for building Python-based web applications, often requires authentication as it scales to handle sensitive data visualizations. This tutorial by Aniket Bhattacharyea demonstrates how to integrate authentication and single sign-on (SSO) into a Dash app using Descope. Descope simplifies the process with its secure architecture and no-code platform, supporting OpenID Connect (OIDC) for easy authentication integration. The guide details the configuration of Descope and the addition of magic link authentication, social login, and SSO using Okta as the identity provider (IdP). By implementing Descope, developers can offload credential management, thus enhancing security and saving development time. The tutorial also explains setting up an authentication flow, fetching user details, and adding a logout button to the Dash app, all while underlining the importance of SSO in maintaining security standards across different organizations' identity providers.
