OpenPass, from Daniel Justus, is a secure command-line password manager designed to centralize vaults and secrets for automation and developer workflows. The tool encrypts vaults with the age protocol, generates TOTP codes at the command line, and injects secrets into shell commands to avoid hardcoding. It includes automatic clipboard clearing, multi-user vault sharing, and a Model Context Protocol server to grant controlled agent access. Target users are developers and system administrators who need scriptable secret management and agent integration.

What tasks can you actually use it for?

OpenPass functions as a developer-oriented vault that provides encrypted storage, one-time code generation, and on-demand secret delivery to processes. In practice the tool produces CLI outputs such as current TOTP values and command exit status when run under its secret execution mode, and it writes an encrypted vault file to disk using its chosen encryption backend. That makes it suitable for scripting, CI steps, and local automation where secrets must be supplied programmatically.

How reliable and auditable are the security outputs?

Encryption and sharing model rely on the age protocol and recipient keys, which the developer selected as a simpler alternative to legacy GPG workflows. Multi-user vault access uses age recipients for shared decryption capability, while automatic clipboard clearing reduces the window that sensitive strings remain accessible in system memory. Those design choices produce deterministic encrypted files and a clear sharing model that teams can audit by reviewing recipient key lists.

What file formats and environment requirements matter?

The tool targets terminal environments and supports desktop platforms through cross-platform builds. When building from source it requires the Go runtime, and typical use assumes a shell session and standard input/output for scripting. Supported deployment scenarios include interactive shells and automated scripts. Example platform targets are:

• macOS
• Linux
• Windows

This setup makes the tool fit CI runners and developer laptops but requires a command-line environment for full functionality.

Does it integrate with AI agents and team workflows?

OpenPass exposes an MCP server endpoint so authorized agents can request specific secrets during a session, and the tool enforces user authorization for those requests. For team workflows, the multi-user recipient model lets multiple keyholders decrypt shared vaults without exporting raw secrets. Those behaviors position the tool for environments where agent-driven automation must obtain credentials under explicit, session-scoped consent.

Practical choice for technical teams seeking programmatic, auditable secret delivery

OpenPass is a pragmatic option for technical teams that prioritize scriptable secret access and explicit session controls for agent interactions. It rewards users who maintain key hygiene and explicit authorization policies, and it requires operator familiarity with terminal workflows. Use it where automation and auditability matter most; teams without command-line expertise should evaluate whether a GUI-oriented alternative better matches their day‑to‑day operations.
