Scilo

A zero-knowledge secrets manager. Store your API keys and passwords once — let Claude Code, Codex, and your terminal fetch them safely, without the plaintext ever landing in an AI agent's context.

Why Scilo

Zero-knowledge

Every secret is encrypted on your device before it ever touches disk. Even a synced copy is unreadable without your master password.

Built for AI agents

Claude Code and Codex fetch secrets through a safe wrapper — the plaintext value is injected into a command's environment, never returned as text an agent can see or leak.

No password re-entry

Enroll a device once, and future unlocks are instant — no retyping your master password every time.

Real revocation

Losing a device rotates and re-encrypts your whole vault, not just a permissions flag — a stolen laptop can't keep decrypting anything.

Connect it to Claude

The desktop app can wire this up for you automatically (Settings → Connect Claude). Prefer doing it by hand? See the manual setup guide for the exact command and config snippet.
