AWS Cli Update Credentials
To run an aws cli update credentials workflow, replace your local keys or refresh your session token. You can edit your local key file or log in through single sign-on.

To run an aws cli update credentials workflow, replace your local keys or refresh your session token. You can edit your local key file or log in through single sign-on. Most teams start by saving static keys on each laptop. Engineers copy these keys from the cloud console into local text files. This setup works for small projects, but it creates big risks later. Over time, teams grant broad permissions to avoid daily login friction. If an attacker steals a local key, they gain those same broad permissions.
How the aws cli update credentials flow works
The command line tool looks for keys in a set order. First, it checks your active shell session for exported key variables. Next, it reads the local credentials file in your home folder. You can store multiple named profiles inside that local text file. Each profile holds a key ID and a secret key string. When keys expire, engineers must run the setup command again. They paste new key values to overwrite the old profile data.
Many teams move away from static keys to use single sign-on. With single sign-on, the tool opens a browser window for login. After you log in, the cloud provider sends back a temporary token. The tool caches this temporary token on your local disk drive. When the token expires, you must run the login command again. The tool also supports assuming roles across different cloud accounts. It uses your base profile to request a new temporary token.
Why static profiles leave security gaps
Native login flows solve the problem of proving who you are. Short-lived tokens are much safer than static keys stored on disk. Yet both methods leave a major gap during active work sessions. Once a token sits on a laptop, any local app can read it. Worse, cloud roles often bundle read and write permissions together.
An engineer might only need to check the status of one server. Still, their active role lets them delete databases or read customer tables. Native cloud logs record API calls only after the action happens. They do not stop a bad command while it is in flight. They also cannot mask sensitive fields like emails or card numbers in output. When raw results return to the terminal, private data appears in plain text.

Moving from local keys to command controls
Fixing this gap requires changing how engineers run cloud commands. Teams should stop saving plain-text keys on every developer machine. Even temporary tokens on disk create a target for local malware. Instead, teams need controls that check each command before it runs.
Good security checks the exact action, not just the user role. A high-risk delete command should pause and wait for peer approval. Output streams should rewrite matched fields like phone numbers or national IDs. This approach keeps daily work fast while blocking mistakes in real time.
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 runs beside those services as an open-source proxy, a sidecar for your Postgres or API. It inspects requests coming in and results going back on the wire.
Your login details and client tools stay as they are while hoop.dev guardrails refuse bad deletes or drops before they run. On responses, hoop.dev data masking rewrites matched sensitive values 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
Where does the command line tool store local keys?
The tool stores keys inside a hidden folder in your user home directory. One file holds secret keys, and another file holds region and profile settings.
Why do my updated keys fail to work in the terminal?
Shell variables override the local key files on your disk drive. Check your active terminal session and clear any old exported key variables.
How often should teams rotate static cloud keys?
Teams should replace static keys at least every ninety days. Better yet, switch to short-lived sessions so no static keys exist at all.
