The article presents an unofficial OpenID Connect provider for Hacker News, allowing users to log in with their HN username. The login process involves generating a unique code that the user must enter into their HN profile, after which they can use faster login methods such as TOTP or email. The service is free for the first 50 registered users and $6/month or $60/year for unlimited users and logins. The author built this to enable semi-anonymous login for projects tailored to the HN community.
