1Password lets Claude log in without seeing passwords

1Password has launched a new browser integration for Claude that lets Anthropic’s chatbot use stored credentials to complete tasks like booking travel or managing online accounts — without exposing usernames, passwords, or other secrets to the model itself.

Called 1Password for Claude, the feature uses what the company describes as a “zero-exposure security framework.” Instead of handing credentials directly to Claude, 1Password says it injects the required login details through a secure channel the agent cannot view. That means Claude can be authorized to use saved information for a specific task, but cannot actually see passwords or MFA one-time codes.

Access is granted per task, and users can approve or deny each request with a single biometric prompt. That still interrupts the flow, but it is less cumbersome than manually taking over to sign in. 1Password says it also scans the page after every autofill to make sure nothing remains exposed in submitted forms before control returns to Claude.

“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. Nothing else in the 1Password vault is reachable.”

1Password for Claude is available now for Mac users on business, family, and individual plans. It requires the 1Password desktop app and browser extensions, along with the Claude desktop app and browser extensions.

1Password vaults can store passwords, passkeys, 2FA codes, API tokens, and personal data such as addresses and financial details. For now, though, Claude access appears to be limited to login-related details. According to 1Password, support for payment cards and identity details will arrive sometime after launch.
