keychain‑store, an open‑source module, now adds full macOS keychain support for Electron apps. The API lets developers read and write secrets straight into the system keychain, using the native macOS security framework.

Electron‑based tools—[n8n](https://dev.to/go/n8n), custom AI agents, or any web‑tech automation workflow—can store passwords, API keys, and other sensitive data in the keychain instead of plain files or environment variables. The update was posted on GitHub with a migration guide and example code.

**Built‑in OS‑level encryption**

The keychain encrypts data with the user’s login credentials and hardware keys, lowering credential‑leak risks compared to local file storage.

**Seamless user experience**

Users grant permission once; the app retrieves secrets automatically on later launches, removing manual env‑file setup.

**Compliance friendliness**

Storing secrets in the keychain helps meet GDPR or SOC 2 requirements around secure storage and access controls.

**Reduced attack surface**

Avoiding plaintext files cuts the chance that a compromised build artifact or misconfigured CI pipeline exposes secrets.

**Cross‑platform parity**

While the macOS update is new, the same repository already supports Windows Credential Manager and Linux Secret Service, giving a unified API across all desktop hosts.

In practice, you can ship an Electron workflow runner that protects its own credentials, making production deployments more robust without extra tooling.

**Q: Does keychain‑store replace environment variables for all secrets?**

A: It can, but you might still use env vars for non‑sensitive data or CI/CD pipelines. keychain‑store is best for secrets that live on end‑user machines.

**Q: Will this work on headless servers or only on desktop Macs?**

A: The macOS keychain requires a user session, so it’s intended for desktop use. For headless servers, consider using a macOS server keychain or another secure store like HashiCorp Vault.

**Q: How do I handle keychain access on first run?**

A: The module prompts the user for permission the first time it writes a secret. Subsequent reads use the stored credential without prompting, provided the user hasn’t revoked access.

**Q: Is this compatible with existing n8n Electron builds?**

A: Yes. Add keychain‑store as a dependency and update the credential storage logic. The API mirrors the existing credential store interface, so the migration is straightforward.
