You run git credential osxkeychain erase to delete saved repo passwords from your Mac. This helper command takes host and protocol details to wipe one specific login item. Engineering teams often rely on this local keychain store to save personal tokens. When those tokens carry broad permissions, one leaked laptop risks your whole code base. Developers also struggle when old tokens expire and block fresh code pushes.
How git credential osxkeychain erase works on macOS
Git uses a helper tool on macOS to talk to the system keychain. When you log in to a remote host, the helper saves your token. Next time you push code, Git reads the token from the keychain. You do not need to type your password again.
When a token changes or expires, the saved entry breaks your workflow. Git tries to send the old key and the remote server rejects it. To fix this, you trigger the erase action on the helper tool. You pass the protocol and host name over standard input to the helper. The helper finds the matching record in your Mac keychain and deletes it. On your next Git action, the system prompts you for a new key.
Why teams need to clear cached Git keys
Developers switch between personal and work accounts on the same machine all day. They also rotate access tokens to follow security rules. If the old token stays in the keychain, Git keeps sending it. Clearing the entry forces Git to ask for the fresh token.
Offboarding is another common reason to clear saved keys from a laptop. When a contractor leaves a project, their laptop might still hold active keys. Teams ask them to wipe their local keychain entries right away. You can also open the macOS Keychain Access app to remove items by hand. Both methods achieve the same result on that single machine.

What local keychain management solves and leaves open
The macOS keychain keeps plain text passwords out of your local Git files. It encrypts your tokens on disk and locks them behind your Mac login. The erase command gives you a clean way to drop dead credentials. This solves the daily pain of typing tokens on every pull or push.
Still, local keychains leave a big gap in team security and control. Once a token sits on a laptop, central teams lose control over it. A developer with a broad token can run destructive commands at any time. The keychain only checks who logs in to the Mac. It does not check what individual commands or requests do in flight. It also cannot log actions or mask sensitive data like emails or card numbers. Security teams must trust that every user clears their own cache on time.
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
Why does Git still push code after I erase my keychain entry?
Git may pull credentials from another local file or an active SSH agent. Check your local Git settings to see if another helper is active. You should also check if your remote URL uses SSH instead of HTTPS.
Does erasing the keychain entry revoke the token on the server?
No, the erase action only deletes the saved copy on your Mac. The token itself stays active on your Git host until you revoke it there. Always revoke lost or old tokens inside your Git host account settings.
How do I stop macOS from saving my Git tokens again?
You must update your Git helper setting to stop automatic keychain saves. Remove the osxkeychain helper rule from your system or user Git settings. After that, Git will ask for your token on every remote action.
