1Password brings Claude logins without exposing passwords

1Password has added support for Claude, allowing Anthropic’s assistant to use credentials stored in 1Password to complete browser tasks without ever seeing the actual passwords.

According to 1Password, passwords never enter Claude’s context or memory, and they are not sent to Anthropic’s systems. When Claude needs to sign in to a site, 1Password shows the user which credential is being requested and why. If the user approves, 1Password fills the credential directly into the page, with access limited to that specific task and revoked once it ends.

The company also says that after a password is autofilled, the app checks that secrets were not exposed on the page.

For now, credit cards and identities are not supported, so Claude can only use logins and one-time codes. 1Password is also updating its browser extension with Agentic Mode, which locks down the extension when a browser-based AI agent takes control. In that mode, the password interface is hidden, and the agent can access logins and one-time codes only with user approval. 1Password says Agentic Mode protects passwords even if the Claude integration is not enabled.

1Password for Claude is available on Mac for individual, family, and business subscribers. Users also need a Claude Pro, Max, Team, or Enterprise plan, along with the 1Password desktop app and browser extension and the Claude desktop app and Claude in Chrome browser extension. Claude can use 1Password logins anywhere Claude in Chrome is able to complete actions. 1Password has published a help document with setup details.
