A new "zero-exposure" browser integration lets Anthropic's Claude agent log into sites on your behalf while keeping passwords and MFA codes hidden from the AI.

1Password has launched a browser integration that lets Anthropic’s Claude chatbot use stored login credentials to complete multi-step tasks — without the AI model ever seeing the actual passwords or one-time codes [1].

For developers and businesses already using Claude for browser-based automation, the practical gap has been authentication: agents hit a login wall and either stall or require a human to step in. This integration is designed to close that gap while keeping credential data out of the model’s reach [1].

How the zero-exposure framework works

1Password built what it calls a “zero-exposure security framework” that injects credentials into a secure channel the Claude agent cannot read directly [1]. The AI is granted permission to use stored details for a specific task, but it cannot view passwords or multi-factor authentication (MFA) one-time codes [1].

Access is scoped tightly. According to 1Password, Claude is granted credentials on a per-task basis, and users approve or deny each request with a single biometric prompt [1]. After every autofill action, 1Password scans the page to confirm nothing in form submissions remains exposed before handing control back to Claude [1].

“The moment an AI agent takes control of the browser, 1Password locks down automatically, limiting access to only the credentials explicitly granted for the current task,” the company said in its press release. “Nothing else in the 1Password vault is reachable.” [1]

Availability and current limits

1Password for Claude is available now for Mac users across business, family, and individual plans [1]. Using it requires the 1Password desktop app and browser extensions, plus the Claude desktop app and browser extensions [1].

At launch, the integration appears limited to login-related credentials [1]. 1Password says support for payment cards and identity details — both of which can be stored in its vaults — will arrive sometime after the initial release [1].
