Use 1Password to sign in to websites with Claude

Learn how to use 1Password to fill your logins when Claude needs to sign in.

1Password for Claude lets Claude sign in to websites on your behalf, without ever seeing your passwords.

When you ask Claude to complete a task that requires signing in, it sends a request to 1Password. 1Password shows you exactly which item Claude is requesting, so you can approve, choose a different login to use, or deny the request.

If you approve, the 1Password browser extension fills your login directly on the website through a secure channel outside the agent’s view, so your passwords stay encrypted in 1Password and under your control. Claude only knows which login it used. Your password and one-time passcodes never enter the model’s context, memory, or Anthropic’s systems.

1Password also locks down into Agentic Mode as soon as Claude takes control of your browser, so only the items you approved for the current task are reachable, and nothing more. When Agentic Mode is activated, you won’t be able to interact with the 1Password browser extension, see inline autofill suggestions, or use 1Password to sign in to other websites.

  2. In the chat, ask Claude to do something that requires signing in. For example, “go to the Amazon website, sign in, and check the status of my latest order”.
