## AI overview

A tutorial showing how to build a Rust CLI that uses Auth0's OAuth 2.0 Device Authorization Flow, then create an Axum API that validates the resulting access token before allowing access to a protected route.

## Source excerpt

Secure your Rust CLI applications with Auth0 Device Code flow and protect your Axum backend endpoints by validating JWTs with Rust's type safety.
