The text discusses integrating OAuth into a Rust application using ngrok, a tool that allows developers to quickly get local web applications online with features like TLS, identity and access management, load balancing, and more. The author built a chat app using the axum framework, Tokio runtime, and other crates, but then used ngrok's Rust Crate to simplify the process of deploying the app online. With this approach, the app can be made public and secure without requiring extensive configuration or setup.
