Introducing Skyline

The password and secret manager for agents that keep working without you.

It's hard to believe we used to manually approve every tool call. Suddenly, our agents can run for hours without any human attention. The more access you give them, the more you can accomplish.

But there's one thing they always get stuck on: authentication. Nothing stops an agent in its tracks more suddenly than a CLI's login expiring or a browser-use agent getting stuck on a login page.

Sure, you can give your agent a few MCPs. But the reality is, the vast majority of digital tasks are still gated behind login forms built for humans. We need a way for agents to get in.

Unfortunately, solutions available today mostly look like this:

Permission popups are annoying enough when you're sitting at your Mac. If it happens at 3 a.m., it's enough to cause your agent to miss an entire night of work.

As a result, agent power users—often through OpenClaw—have resorted to workarounds that involve a single bearer token giving them the ability to print all of your passwords. This doesn't just mean that the agent sees your password each time (already problematic); it also means malware on your device can steal that .env file and use it to print your entire vault of passwords. Not good.

Oops, I just saw the password. You should change it ASAP.

The goal isn't just fewer approval popups. It's letting an agent keep working on its own without handing it—or anything else on its computer—permanent access to your passwords.

A secure way for agents to access the rest of your accounts.

Skyline lets the agents you already use (and nothing else on your computer) complete login and signup forms without ever seeing a password.

Instead of being limited to a shortlist of MCPs and CLIs, Skyline serves as an inventory of all services available to your agents — every account you have. Imported directly from 1Password, Apple, or Google.

It gives agents a complete picture of what's possible. It's the last unlock that lets agents accomplish anything from a prompt box that you used to do manually.

Skyline is built using a “zero knowledge” architecture, so your passwords stay safe, the keys stay locally on your computer, and your vault is protected from both online hacks and local malware.

Best of all, Skyline works with the agents you already use—Codex, Cowork, Claude Code, OpenClaw, and others.

Your agents can browse in Chrome just as they normally would. When they reach a login or signup page, Skyline swoops in to complete the form, then hands control right back. The agent never stops and never sees a password.

Only these apps can use Skyline
Login completed. The agent did not see the password.

Skyline can also help an agent set up a direct integration. It can sign in to finish OAuth, or create a scoped API key and save it for later use—without the raw credential appearing in its output.

Things you can do with Skyline

Personal

Delete old accounts

Work through old accounts on four familiar services, signing in and reaching each deletion flow without exposing credentials to the agent.

Delete my old Yahoo, Tumblr, Meetup, and Quora accounts. Ask me before each final confirmation.

Test an OAuth flow

Run an end-to-end browser test through the real Google login UI, then confirm the app returns to the expected signed-in state.

Test our Google OAuth signup flow end-to-end in Chrome and report anything that breaks.

Create & use an API key

Create a narrowly scoped key, capture it directly into Skyline, then use it from the StackLane CLI without handing the raw value back to the agent.

Create a project-metadata-only StackLane key, save it in Skyline, then use it with the local CLI to check our production deploy metadata.

What makes it secure

Skyline's security model starts with local decryption keys, an off-device checkpoint before release, local password filling that keeps credentials away from the agent, and verified app access instead of bearer tokens.

Skyline's cloud can see the routing metadata needed to work, such as an account name, URL, label, or pending approval. But it doesn't hold the keys that open protected values and can't decrypt your passwords.

  1. Local-first

    The cloud stores encrypted packages and coordinates their release, but it doesn't hold the keys that open your passwords.

  2. Protection against local malware and prompt injection.

    Every request passes through a checkpoint away from the requester before encrypted material is released. It can deny, delay, limit, freeze, or escalate suspicious requests when the agent or its computer may have been steered in the wrong direction.

  3. Agents don't see your passwords.

    Skyline fills passwords locally, outside the agent's normal context, transcript, tool output, or model-provider logs.

  4. Verified apps only; no bearer tokens.

    Skyline authorizes app and process identities observed on the Mac. A copyable token string isn't enough to use your vault.

Together, these protections let agents use accounts unattended without giving the agent, its computer, or a copyable token standing access to your vault.
