Secret manager for macOS (developer-focused)

“Secret manager” means different things to different teams. On macOS, you already have Keychain, FileVault, and biometrics — so before you add software, it helps to map layers.

This page explains how those pieces fit together and where a developer-first secret manager such as PassStore belongs.

Layers of protection on a Mac

Layer	What it helps with
FileVault (full-disk encryption)	Stolen powered-off laptop resistance
Screen lock / strong password	Casual physical access while you are away
Keychain Services	OS-managed storage for passwords and tokens
Encrypted app vaults	Structured secrets with app-specific UX
Cloud secret platforms	Team RBAC, audit, rotation automation

No single layer replaces the others.

Apple Keychain — when it is enough

Keychain is excellent for:

Wi‑Fi passwords
Safari-stored logins
Certificates and code-signing identities

For developer workflows (dozens of API keys per repo), raw Keychain usage via security CLI scripts becomes fragile. Most teams want a purpose-built UI with workspaces — see macOS Keychain for developers.

What to look for in a macOS developer secret manager

Encryption at rest with modern algorithms (authenticated encryption, strong KDF).
Keychain integration for the most sensitive items.
Local-first operation — works offline; no mandatory cloud for daily dev.
Honest threat model documentation.

PassStore’s model is summarized in Security overview:

AES-256-GCM vault encryption.
Argon2id for password-derived key wrapping (current vaults).
Keychain for sensitive values per platform conventions.
Explicit about not magically stopping malware on a fully compromised, unlocked machine.

Local-first vs syncing your secrets to a vendor

Some tools sync secrets through their cloud by default. That can be fine — but it is a different threat model (vendor security, legal jurisdiction, SSO requirements).

If your priority is privacy and speed on a single Mac, evaluate tools that keep canonical dev material on-device unless you opt into export/backup.

Habits beat products

Software cannot save you from:

Pasting a prod key into Slack
Committing .env “just once”
Using sk_live_ in local dev because “it was easier”
