1Password has introduced “1Password for Claude,” a browser integration that lets Anthropic’s Claude sign in to websites using credentials stored in a 1Password vault. According to multiple reports, the feature follows a “zero-exposure” design in which Claude is not given direct access to passwords or authentication codes. Instead, when Claude needs to log in, the system prompts the user to approve the specific credential request. After approval, 1Password fills the required username and password (and associated authentication inputs, such as one-time codes) into the target website while restricting access to the rest of the vault and preventing credentials from being shared with Claude’s model, memory, or Anthropic’s systems. Several outlets also describe a related “Agentic Mode,” which limits what an AI agent can do during browser sessions to actions using approved credentials. The coverage also notes that, while credentials are not exposed to the AI, the authenticated agent may still be able to view or modify data that the logged-in account allows, meaning risks related to account access are not eliminated. The feature is reported as available for macOS setups and for certain 1Password and Claude plan tiers, with additional support planned.
