The aws credentials folder is a hidden directory inside your local user home path. It stores plain text files that hold secret keys and settings for cloud tools. Engineering teams often set up this directory during onboarding so developers can run local scripts. Still, storing long-lived keys with broad role permissions on laptops creates a major security risk.
How the aws credentials folder works in local workflows
When you install the official command line tool, it looks for this hidden home folder. Inside that folder, the tool splits information across two separate plain text files. One file holds your secret keys, while the other holds region and output choices. You can group these settings into named profiles for different accounts or project teams.
Local apps and software development kits read this folder by default when they start up. The tool checks environment variables first and then falls back to the local files. If a developer picks a named profile, the tool reads the matching keys from disk. It then uses those keys to sign every request sent to the cloud provider.
Teams also use this folder to store temporary tokens from single sign-on logins. When a user logs in through a browser, the tool writes short-lived keys to disk. Other local tools can then read those temporary keys to run commands or deploy code. This pattern keeps multiple local tools working together without asking the user to log in again.
What the local folder solves and where it falls short
The local folder gives developers a simple way to manage keys across many cloud accounts. An engineer can switch between a test account and a production account in seconds. Every local script and development kit checks the same standard place to find login keys. This shared standard stops teams from hardcoding secrets directly inside their source code files.
Despite this convenience, local key files leave a wide operational gap for security teams. Any script, dependency, or malware running under that user account can read the plain text keys. Even when teams use single sign-on, cached tokens sit on the laptop until they expire. If an attacker steals those files, they gain the full power of that cloud role.

More importantly, cloud identity roles only decide who can log in to a target service. Once a developer connects to a database or cluster, the cloud role steps out of the way. The local folder setup cannot check what individual queries or commands do in flight. A developer with valid keys can still run a bad query or pull sensitive records.
Managing profile permissions and reducing local key sprawl
To lower the risk of stolen files, teams should remove static keys from user laptops. You can link your cloud accounts to a central identity provider for daily human logins. This change replaces permanent secret keys with temporary session tokens that expire after a few hours. You should also remove unused profiles from the local directory on a regular schedule.
Even with short-lived tokens, broad cloud roles still give users too much power during a session. A role that allows database logins cannot stop a user from reading private customer tables. It cannot mask emails, phone numbers, card numbers, or national IDs in query results. True safety requires checking and logging every command and query at the moment it runs.
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
Where does the system put the aws credentials folder by default?
The system places this hidden directory directly inside the home folder of your current user account. Both Unix systems and Windows machines follow this same home folder convention for each local user.
What is the difference between the two files inside the folder?
One file stores your sensitive access keys and session tokens for each named profile. The second file stores non-secret settings like your default cloud region and preferred text output format.
How can teams protect the keys stored inside the local folder?
Teams should stop using long-lived static keys and switch to short-lived single sign-on sessions instead. You should also restrict file permissions so only the file owner can read the local directory.
