Identity security company 1Password today launched 1Password for Claude, a browser integration that lets Anthropic PBC’s Claude use a person’s stored logins to complete online tasks without those credentials ever reaching the artificial intelligence model.

The tool targets a problem that has grown as AI agents begin acting on people’s behalf. To let an agent sign in somewhere, users have generally had to paste credentials straight into the agent’s context, where the model can read them. The other option was stopping to authenticate by hand at every step.

1Password for Claude drops that tradeoff. Credentials are injected into the target site through a secure channel that 1Password controls, and the password and any multifactor onetime code stay outside the model, its memory and Anthropic’s systems.

Access is granted per session and scoped to a set of approved items. It does not carry into other sessions and it leaves no standing access behind. Claude requests the credentials it needs for a given task and the user approves or denies each request with a single biometric prompt.

“We need a new security model that is purpose-built for agents, not just humans,” Chief Technology Officer Nancy Wang said in the announcement. “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.”

The integration runs on what 1Password calls a zero-exposure security framework. Alongside it, the company is introducing a feature called Agentic Mode for all users. The moment a compatible agent takes control of the browser, the vault locks down. Only the credentials granted for the current task stay reachable. Nothing else is accessible.

Agentic Mode turns itself on and stays active while an agent works. Users can see it running in the 1Password browser extension and switch it off whenever they want.

Two other features fill out the release. 1Password brokers credential access across multiple sites inside one task, so Claude can move through multistep workflows without asking for logins again. It also scans each page after every autofill and wipes any filled values if a form submission fails, cutting off a common way for secrets to linger on screen.

1Password says Agentic Mode starts with Claude and is built to extend to other browser-based agents as the market grows. 1Password for Claude is available now to 1Password users on Mac across business, family and individual plans. It requires the 1Password desktop app and browser extensions along with the Claude desktop app and browser extensions. Support for payment cards and personal details such as names and addresses is due after launch.

The company’s enterprise vault holds more than 1.5 billion credentials and secrets and is used by more than 1 million developers and 180,000 businesses, including Figma Inc., GitHub Inc., MongoDB Inc., Notion Labs Inc., Perplexity AI Inc., Salesforce Inc. and Stripe Inc.
