Hhvm SSO
You set up hhvm sso by linking your web server to an identity provider. Your app or server then checks user tokens before it grants login rights. Many teams add an OAuth or SAML module to their Hack code. Others place a login filter on the web server in front of the engine.

You set up hhvm sso by linking your web server to an identity provider. Your app or server then checks user tokens before it grants login rights. Many teams add an OAuth or SAML module to their Hack code. Others place a login filter on the web server in front of the engine. When teams grant broad roles during this setup, one login opens too many doors. Users get full rights to run server scripts or read all database tables.
How hhvm sso works in your stack
HHVM runs Hack code to serve fast web pages and background jobs. The runtime engine itself does not store user accounts or check group logins. Instead, your team must build login checks into the surrounding stack. You start by registering your web app with your company identity provider. When a user visits the site, the app sends them to the login page.
After the user logs in, the identity provider sends a signed token back. Your Hack code or web server reads this token and checks the signature. It then extracts the user email and group role from the token payload. The app matches these group roles against an internal list of allowed actions. For example, an admin group might get rights to view the server admin port. Developers also use single sign-on to reach hosts that run the engine.
What native login solves and what it misses
Setting up single sign-on stops your team from sharing static passwords across servers. When an engineer leaves the company, you disable one account in your identity tool. That single action blocks their login to your web apps and server hosts. It also forces users to pass a second factor check before they start work. This setup solves the basic problem of proving who is at the keyboard.
Still, login checks only guard the front door of your system. Once a user logs in, the native setup stops watching what they do next. If an engineer has a valid session, they can run any command allowed by their role. A broad role lets them query production data or run heavy scripts without review. The login tool cannot pause a risky command to ask a manager for approval.

Closing the gap in runtime scripts and queries
Real safety requires checking each action after the login finishes. Engineers often need to debug live Hack code or check server state during an outage. If you only rely on group roles, you must give them full server rights all day. A better path separates the login step from the actual command execution. Teams need a way to inspect individual requests and scripts in flight.
When a script or query runs, the system should log the exact user identity. It should also check if that specific action needs a quick peer review. If a query returns sensitive fields, data masking can rewrite emails or card numbers in results. This approach keeps production data safe while developers fix bugs on live servers. You keep the speed of single sign-on while adding tight controls on runtime actions.
Add runtime guardrails and masking beside your databases and APIs
Login rules, role grants, and CI checks govern who connects to your stack. Yet any allowed script, engineer, or AI agent still runs commands with the full scope of its role. For workloads on Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes, SSH, or internal HTTP services, hoop.dev sits beside the service as an open-source proxy, a sidecar for your database or API.
Before a query runs, hoop.dev guardrails check the statement against your rules. An AI Analyzer you configure can score intent or hold risky calls for human review. Next, hoop.dev data masking rewrites sensitive fields in responses, and each verdict is logged per listener. Explore the MIT-licensed project on GitHub.
Frequently asked questions
Does the HHVM engine include built-in SAML or OIDC support?
No, the engine runs Hack code and does not include native identity modules. You must use a Hack library or a web server module to check tokens.
How do we secure the HHVM admin server port with single sign-on?
You should bind the admin port to localhost so public traffic cannot reach it. Then require engineers to log in with their identity provider before they reach that port.
Can single sign-on mask sensitive data in Hack app logs or queries?
No, an identity provider only checks who logs into the system at the start. To rewrite phone numbers or national IDs in results, you need a runtime masking tool.
