A password manager your AI agents can use, without seeing your passwords
Coding agents now test logins, check dashboards and query databases. They need your credentials to do it, and the easy ways to hand them over put the secret in the model's context. Here is how the options compare.
Side by side
| OTPilot | 1Password | Bitwarden MCP server | Pasting into the chat | |
|---|---|---|---|---|
| The model sees the password | No | No | Yes: items are returned to the agent | Yes |
| 2FA codes in the same flow | Yes | Yes | Returned to the agent like any field | You type them |
| Approve each agent and each account | Yes, per agent and per account | You approve each request (1Password for Claude) | No: the agent reaches the whole vault | No |
| Terminal agents (Claude Code, Codex, Cursor) | Yes, through MCP | Environments MCP server and CLI | Yes, through MCP | Yes |
| Sign in to websites for the agent | Yes, the agent's browser gets the session | 1Password for Claude (Mac) | No | No |
| Free plan | Yes: 1 agent, 3 accounts | No (14-day trial) | The server is free; 2FA codes need Premium | Free, and risky |

Why "the model never sees it" matters
Whatever enters an agent's context can end up in the transcript, your history, logs and the model provider's systems, and a prompt injection on any page the agent reads can try to get it repeated somewhere else.
OTPilot's tools never return a secret. The agent asks to sign in or to run a command, OTPilot does it with the real values, and returns the result: "signed in", or the command's output with secrets scrubbed.
How OTPilot does it
- Two approvals. An agent connects with a code you check in the extension, and gets no accounts. Each account is a separate approval for that agent.
- Encrypted for that agent. An account you allow is encrypted for the agent's own key, kept in your keychain. Our servers only see ciphertext; revoke it and the agent can no longer open it.
- Scope and time. Allow just the 2FA code, the whole sign-in or chosen fields; for an hour or until you revoke; or ask every time.
- Only on the right site. A sign-in is only made on the site saved in the account.
- Activity log. Every use, by agent and account, with one-click revoke.
The honest limit
An agent that runs commands chooses what those commands do, and could try to reveal a secret on purpose. No password manager can fully prevent that. OTPilot narrows it: secrets are scrubbed from what it returns, and for sensitive accounts you can allow only the 2FA code, limit the commands, or approve every use.
Questions
- Which agents does it work with?
- Any agent that supports the Model Context Protocol (MCP): Claude Code, Codex, Cursor, Claude Desktop and others.
- Does the agent use the browser extension?
- No. You manage agents and accounts in the extension; the agent only talks to the OTPilot MCP server on your computer.
- How much does it cost?
- Agents are in every plan: Free connects 1 agent with up to 3 accounts, Personal ($3/month) and Team have no limit.
