🔗 OAuth 2.0 – device flow explained for engineers, especially for backend engineers

A frustrating login experience with long passwords on devices led to the development of OAuth 2.0 device flow. This flow provides a practical solution for scenarios where typing passwords is unfeasible, such as on smart TVs or IoT devices.

The article details how to implement this flow step-by-step using a command-line interface called mycli. It breaks down how to handle the authorization process effectively, manages polling, and explains the various server responses that developers must anticipate.

With real-world examples of how this flow enhances user experience, the piece serves as a guide for backend engineers to streamline authentication processes for users facing input constraints, ultimately urging developers to implement it in their applications.
