1Password lets Claude log you in without seeing passwords
1Password’s new Claude integration lets Anthropic’s assistant complete logins with biometric approval, while keeping passwords out of the model’s memory.

1Password has introduced 1Password for Claude, a new integration with Anthropic that lets Claude authenticate on a user’s behalf without ever seeing the underlying credentials.
The company says the tool is built on a “zero-exposure architecture.” In practice, Claude can ask 1Password to handle a sign-in, but the password itself is never exposed to the assistant and is never loaded into its memory. Before anything happens, the user gets a notification and must approve the login with biometrics. Once approved, 1Password autofills the credentials, checks whether they were exposed on the page, and, if submission fails, clears the filled values and reports back.
“We need a new security model that is purpose-built for agents, not just humans,” said Nancy Wang, CTO of 1Password. “The answer isn’t handing agents your secrets. It is to let a user give an agent permission to use a credential without letting the agent see it. Claude knows it used your login; it does not need the password or one-time code in its context. That distinction is where trust in agents starts and the foundation we’re building with Anthropic.”
1Password also announced Agentic Mode for its browser extension. When a compatible browser-based agent takes over, the extension automatically locks down and hides its interface. The agent can only use logins and one-time passwords that the user has explicitly approved for the current task.
According to 1Password, Agentic Mode works even if the Claude integration is not enabled and even when 1Password is not required for the task. The feature also supports agents beyond Claude.
The launch lands as companies debate how much access software agents should get and under what safeguards, especially after reports of agents deleting email inboxes or disrupting other work.
