An aws cli federated user logs into cloud accounts with short-lived tokens from an identity provider. You set this up by linking your single sign-on tool to cloud roles and local profiles. Teams use this approach so engineers do not store static keys on their laptops. Still, broad cloud roles often give engineers too much power once they log in.
How an aws cli federated user session works
First, an admin sets up a trust link between the cloud account and the identity provider. This trust link relies on open standards like SAML or OIDC to check user identities. Next, the admin maps groups from the identity directory to specific cloud roles. Each cloud role holds policies that define what resources a user can read or change.
On the local laptop, the engineer sets up a named profile in their command line tool. This local profile points to the single sign-on portal and names the target role. When the engineer starts a work session, the tool opens a browser window for login. The identity provider checks the password and prompts for a second factor.
After a valid login, the identity provider sends a signed assertion back to the cloud token service. The cloud token service checks the signature against the trust link. It then issues a temporary access key, a secret key, and a session token. The command line tool caches these temporary keys on the local disk for a few hours. Every command the engineer runs uses these cached keys until the timer runs out.
Where native role mapping falls short in daily work
Native federation stops engineers from pasting long-lived keys into local text files. When a person leaves the team, disabling their single sign-on account cuts off future logins. This setup solves the problem of initial entry and centralizes user management.
Still, federation only checks who logs in at the start of a session. Once the token sits on the laptop, the user has full access to that role. Teams rarely create a unique cloud role for every single task or incident. Instead, they create broad roles for developer groups or on-call responders.

A broad role lets an engineer run any allowed command for the entire token lifespan. Cloud audit logs record that the role called an API, not why it happened. If an engineer queries a database or reads a storage bucket, raw data returns intact. Native role tokens cannot rewrite sensitive fields like emails, phone numbers, or card numbers in flight. They also cannot pause a single risky command for peer approval while allowing safe read commands.
Why local token caches create blind spots
Local token caches also create a risk on the engineer's machine. Any local script or app running under that user account can read the cached token file. If a bad package runs on the laptop, it can use those tokens right away.
Revoking an active session across many accounts takes extra manual steps in the cloud console. Admins must attach deny policies to the role and wait for them to take effect. Meanwhile, the engineer or script can still run commands until the token expires or refreshes.
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 sits inline in the protocol beside each supported service as an open-source proxy, a sidecar for your database or API. For every query or command an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human approval.
First, hoop.dev guardrails block banned queries before they run or hold risky ones for review, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
What is the difference between an IAM user and a federated user?
An IAM user exists inside a single cloud account and often uses permanent keys. A federated user logs in through an external identity provider and receives temporary session tokens.
Where does the command line tool store temporary session tokens?
The tool writes temporary tokens into a hidden folder inside the user's local home directory. It reads from this local cache on every command until the session expires.
How do you stop an active federated session before it expires?
Signing out of the identity portal does not kill tokens that are already minted. You must add a time-based deny rule to the cloud role to block active tokens.
