Duende BFF Security Framework enhances web application security using the Backend-for-Frontend (BFF) pattern. It routes authentication through a secure server-side component, protecting tokens from client exposure and reducing attack surfaces. It supports OAuth 2.0 and OpenID Connect, offering secure session and token management for both SPAs and traditional apps. With Duende's server-side Backend for Frontend (BFF) solution you can easily manage tokens on the server—not in the browser to simplify your front-end development and increase security for Angular, React, Vue, and Blazor WASM apps.
