Free IdP
A free idp lets you manage user logins across all your apps at zero cost. You can set up an open-source provider or use a hosted free tier. Most teams start by linking their email tool or code host to one login page. They then create groups for devs, admins, and support staff. If you make those group roles too broad, users get too much power inside target systems. One stolen login can then put many databases and servers at risk.

A free idp lets you manage user logins across all your apps at zero cost. You can set up an open-source provider or use a hosted free tier. Most teams start by linking their email tool or code host to one login page. They then create groups for devs, admins, and support staff. If you make those group roles too broad, users get too much power inside target systems. One stolen login can then put many databases and servers at risk.
How a free idp handles user logins and roles
An identity provider acts as the single source of truth for your team directory. When a user tries to open an app, the app sends them to the login server. The user types their password and passes a second check on their phone. The provider checks these details against its user store. If the check passes, the provider builds a signed digital token. This token lists the user email, name, and group names.
Most setups use standard web protocols like OIDC or SAML to send this token. The target app reads the signature on the token to make sure it is real. Next, the app maps the group names in the token to its own local roles. For example, a dev group might map to a read-write role in a database tool. An admin group might map to a full control role in a cloud console. You only have to add or remove a user in one central place. When someone leaves the team, you block their account in the provider. That single step stops them from logging into any linked app.
Choosing between self-hosted and cloud options
Teams looking for a no-cost login tool have two main paths. You can run an open-source server on your own cloud hosts. This path gives you full control over user data and has no user limits. Still, your team must patch the server, back up the database, and keep it online. If that login server goes down, nobody can sign into their work tools.
The second path is a free plan from a cloud identity vendor. Here, the vendor runs the servers and handles updates for you. The trade-off is that free cloud plans cap how many active users or apps you can add. They may also hold back features like automated user sync or custom login rules. Small teams often start on a cloud free tier to save setup time. Larger teams with strict data rules often pick the self-hosted path.

What an identity provider solves and what it leaves open
A central login tool solves account sprawl across your company. You no longer need to create separate passwords for every database, server, and dashboard. It also enforces strong password rules and two-factor checks in one place. Auditors can look at one user list to see who belongs to which group.
Still, the identity provider stops working once the login step finishes. It decides who can enter an app, not what they do inside a live session. After a dev logs into a database or server, the provider sees nothing else. It cannot inspect individual SQL queries, shell commands, or API calls in flight. If a role allows read access, a user can dump a whole table of customer emails. Data masking is needed to rewrite sensitive fields like phone numbers or card numbers in query results. Teams also need command-level logs and step-up approvals for risky actions during active work.
Check database and API queries on the wire
Identity tools, roles, and network rules decide who opens a session. Setup alone cannot check what each query does or mask sensitive values in a response once a session starts. When workflows touch Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, or internal HTTP APIs, hoop.dev sits inline in the wire protocol beside those services as an open-source proxy, a sidecar for your Postgres or API. On every query an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human review.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II, is MIT licensed, and writes every query and decision to an audit trail that generates evidence for HIPAA, GDPR, and PCI DSS. See the source on GitHub.
Frequently asked questions
What is the difference between OIDC and SAML in a free idp?
Both protocols let your provider send signed login tokens to your apps. SAML is older and uses XML messages, which many legacy enterprise tools require. OIDC is newer, runs on JSON, and works well with modern web and mobile apps.
Can I use a free idp for database and server logins?
Yes, if your database or server tool supports external identity providers like OIDC or LDAP. Still, the provider only checks the user at the start of the session. It does not log individual queries or block risky commands after login.
What happens when a team outgrows a free cloud tier?
When you hit the user or app limit, you must upgrade or move to another tool. Moving means you have to set up trust links for every connected app again. To avoid this work, check the user caps and feature limits before you start.
