Where Does AWS Cli Store Credentials
The tool saves secret keys in a plain text file inside a hidden home folder. When teams ask where does aws cli store credentials, the answer is the user directory. On Linux and macOS, this hidden folder sits inside the main user home path. On Windows, the same hidden folder lives inside the main user profile directory. The tool separates secret keys from basic settings like region and output format. Secret keys go into the credentials file, while general settings go into the config file. Unde

Understanding where does aws cli store credentials in daily work
Engineers and AI agents rely on a strict lookup order to find valid keys. The command line tool does not check the local credentials file first. Instead, it checks several places in a set order until it finds valid keys.
First, the tool looks for options passed directly in the command line. Second, it checks shell variables set in the active terminal session. Third, it checks for single sign-on tokens cached in a local folder. Fourth, it reads the shared credentials file and then the shared config file. Finally, if the code runs on a cloud server, it checks the server role.
Users can store multiple named profiles inside the local files for different accounts. One profile might hold keys for a test account, while another holds production keys. When an engineer or AI agent runs a command, it picks the default profile. To use another account, the user tells the tool which profile name to read. Single sign-on setups work in a similar way by saving short-lived tokens to disk. The tool reads those cached tokens from a subfolder inside the main hidden directory.
Security risks of local files and active sessions
Storing static keys in plain text files on a laptop creates clear security risks. Any local app, script, or malware running as that user can read the file. If an engineer backs up their home folder to the cloud, keys can leak. AI coding agents that read local files can also pull these secrets into prompts.

Cloud roles and single sign-on help reduce the risk of long-lived static keys. Still, local token caches still live as plain files on the user machine. Once a session starts, the active role grants broad permissions across cloud resources. Cloud identity rules only check who starts the session, not every single action inside. For example, a role might let an engineer connect to a production database. Identity rules alone cannot stop an accidental drop table command or mask sensitive data. Standard cloud roles also do not rewrite emails, phone numbers, or card numbers in query results.
Better ways to handle cloud keys for teams and agents
Teams should avoid saving long-lived access keys in plain text files on user laptops. Using short-lived sessions through single sign-on is a strong first step for any team. Engineers should also set strict file permissions so other local users cannot read keys.
When AI agents or automation scripts run cloud tasks, they need tighter controls. Granting an agent a broad local profile puts every linked cloud resource at risk. Teams need a way to run commands without putting raw keys on the laptop. They also need fine-grained checks on every query or command sent to cloud resources.
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
Can I change the folder where the tool looks for keys?
Yes, you can set a shell variable to point the tool to another file path. This lets you keep secret files outside the default home folder on your machine.
Are keys in the local credentials file encrypted by default?
No, the command line tool writes keys in plain text inside your home directory. Anyone with read permissions on your user account can open and copy those keys.
Which wins if keys exist in both shell variables and the local file?
Shell variables always win over the local credentials file during the lookup process. The tool stops searching as soon as it finds valid keys in your active shell.
