Every product carried its own login, its own password rules and its own role table — users had to re-register per app and admins had no unified view of access.
The AI-powered solution
HN Group consolidated identity into a single OAuth2/OIDC provider with row-level-security-backed roles, magic links, Google sign-in and refresh-token rotation, live on its own domain within 24 hours.
Impact & results
Sign-up friction down 62%, support tickets about lost logins eliminated, and every new subdomain inherits auth in minutes.
