The default aws cli credentials file location sits inside a hidden folder in your home folder. On Mac, Linux, and Windows, the tool reads keys from this path during each command. Teams often put static keys in this file so engineers can run local tasks fast. Still, wide roles on those keys create big security risks if a laptop gets lost.
How the aws cli credentials file location works
When you run a cloud command, the tool looks for keys in a set order. It checks shell variables first before it reads your local disk files. If it finds no shell values, it goes to the aws cli credentials file location. On Mac and Linux, this hidden folder sits right inside the user home path. On Windows, the same hidden folder sits inside the main user profile directory.
The tool splits your local setup across two plain text files in that folder. One file holds your secret keys and token values under named profile sections. The second file stores your region choice and output format for each named profile. You can switch between accounts or roles by naming a profile when you run commands. You can also change the file path by setting a custom shell variable.
How the default credentials chain handles profiles
Many engineers work across test, staging, and prod accounts during a single day. The local credentials file lets them group each key pair under a clear profile header. A default profile runs when the user does not pick a specific name. Named profiles can also point to an assumed role in another cloud account. When triggered, the tool uses the base key to fetch a short token.
The tool caches that temporary token in another subfolder inside the same home directory. Later commands reuse the cached token until the clock on that session runs out. Single sign-on setups follow a similar flow and write short tokens to local disk. This setup keeps daily terminal work smooth across many cloud accounts and regions.

What local credential files solve and what they miss
Storing profiles in a standard home folder solves the basic login problem for engineers. Scripts and local apps know right where to find keys without extra setup steps. Role switching in the config file also cuts down on manual copy and paste work.
Still, plain text files on laptops leave a big gap in day-to-day safety. Anyone or any bad script with user access can read those stored keys. Even when teams use single sign-on, a live session grants full role power. The native login flow only checks who starts the session at the front door. It does not check or limit what each command does once the session starts. A user with a broad role can still drop tables or read private data. Static files also cannot mask emails, phone numbers, card numbers, or national IDs in output. Teams need controls that inspect commands in flight and remove static keys from laptops.
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
Where does the tool store credentials on Windows vs Mac and Linux?
On all systems, the tool uses a hidden folder inside your main user home directory. Mac and Linux place it in the home path, while Windows uses the user profile folder.
What is the difference between the credentials file and the config file?
The credentials file stores your secret access keys and session tokens for each profile. The config file holds non-secret settings like your default region and output text style.
Can I move the credentials file to a custom folder path?
Yes, you can point the tool to a new path using a shell variable. Once set, the tool reads keys from your custom file path instead of the home folder.
