This blog was originally published on Descope . Need to add authentication to your command-line tool? Most command-line applications rely on API keys, manual token management, and other methods that create friction for users who just want to get authenticated. In this blog, we'll walk through the challenges of CLI authentication and how to implement it seamlessly with Descope Inbound Apps. We'll also show how to bring OAuth 2.0 directly to your CLI app with code examples in Go. What is CLI authentication? In the context of command-line applications, authentication presents a unique challenge: how do you securely authenticate users in an environment that traditionally lacks the interactive elements of web applications? Most CLI tools handle this via the tedious storage of API keys in configuration files or environment variables. This approach creates friction for users and introduces security risks as a byproduct of storing credentials in plain text or across systems.…
