Openid Identity Provider
An openid identity provider checks who a user is and sends signed tokens to your apps. You set one up by linking your user list, registering each app, and mapping group claims.

An openid identity provider checks who a user is and sends signed tokens to your apps. You set one up by linking your user list, registering each app, and mapping group claims. Most engineering teams use this setup to keep passwords in one central place. Still, teams often attach broad group roles to these login tokens to move fast. When one role grants wide permissions, any user in that group can run risky commands.
How an openid identity provider works in practice
The login flow starts when a user tries to open an internal tool or database client. The app redirects the user to your central login server to check their identity. The user enters their password and passes a second check, such as a phone prompt. Once the server confirms the user, it creates a signed JSON token with user details. This token holds the user email, group names, and a short expiration time.
Next, the login server sends a single-use code back to the waiting app. The app trades this code for the signed identity token over a secure channel. Your app reads the cryptographic signature from a public endpoint to trust the token. Then the app reads the group claims inside the token to pick a local role. The user is now logged in, and the app trusts them until the token expires.
Setting up claims and group roles for your team
To make this work for engineers, you map directory groups to claims inside the token. First, you create clear groups in your main user directory for each job type. For example, you might make separate groups for backend devs, data analysts, and site admins. Next, you tell the login server to include these group names inside every identity token. Each downstream tool or database reads that claim list when a person logs in.
Many teams hit trouble here because they create too few groups for daily work. Making a new group for every single table or server takes too much time. Instead, admins map one dev group to a broad admin role in the target system. This keeps the initial setup simple, as engineers do not get blocked by missing permissions. Yet it also means every developer gets full write power across your production systems.

What native login solves and the gap it leaves open
A central login server does a great job of proving who a person is. It stops teams from sharing static passwords or saving plain keys on laptops. When an employee leaves the company, you can turn off their account in one place. It also gives you a clear log of when each user signed into an app.
Still, the login server stops watching as soon as the user gets inside the system. It decides who can log in, not what commands or queries they run next. Once a database or server accepts the token, the user holds that role for hours. The login server cannot stop a bad delete query or mask emails and card numbers. To control actual actions in flight, you need checks at the command level.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev runs beside each supported service as an open-source proxy, a sidecar for your database or API.
First, hoop.dev guardrails block banned queries before they run. Then hoop.dev data masking rewrites matched sensitive values in responses in memory. The audit trail records every statement and verdict per resource. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
How is an OpenID provider different from plain OAuth?
OAuth lets an app act for a user by granting permission tokens for specific tasks. OpenID sits on top of OAuth and adds a signed token that proves user identity.
What happens when an identity token expires during a work session?
When the short identity token expires, the app checks if the user has a refresh token. If the user is still active in the directory, the server sends a fresh token.
Can an identity provider hide sensitive data inside a database query?
No, a login server only handles the initial sign-in step and passes group claims. It never inspects live SQL queries or rewrites phone numbers and national IDs in results.
