1Password is launching a browser integration for Anthropic’s Claude. The AI chatbot can use stored login credentials to perform tasks without actually seeing the passwords themselves. A new “zero-exposure security framework” is designed to prevent leaks. The feature is now available on Mac.
Logging in is often a stumbling block for AI agents. As a human, you usually have to step in to grant the agent access. 1Password can now eliminate this friction. With 1Password for Claude, the chatbot can handle more complex tasks, such as booking a trip or managing online accounts. The user authorizes Claude to do this, but Anthropic’s AI models never actually see the security credentials themselves.
Technical details
It revolves around a new framework developed by 1Password. The necessary login credentials are injected per task via a secure channel, which the Claude agent cannot access. As explained by 1Password, this channel is built on the Noise Framework, an end-to-end encrypted connection between the authorizing device and the browser extension. This way, the model never sees any passwords or MFA codes.
Access is granted on a per-task basis, with a single biometric prompt sufficient to approve or deny a request. 1Password also scans the page after each autofill to ensure nothing is left behind in forms.
“The moment an AI agent takes control of the browser, 1Password automatically locks,” the company stated in its press release. Only the data explicitly granted for the current task remains accessible.
More and more AI integrations
1Password previously launched Unified Access Pro to securely manage secrets for both humans and AI agents and machine identities. At that time, the company already mentioned its collaboration with Anthropic and OpenAI. For Anthropic, this is one of many integrations Claude has received, including integrations with Google Workspace and Slack. Anthropic is also targeting integrations with a wide range of sectors, such as education, science, and, of course, coding.
1Password for Claude is now available for Mac users. Both the desktop app and browser extensions from 1Password and Claude are required. For now, access appears to be limited to login credentials; support for payment cards and identity information will follow after launch.
