1Password announced 1Password for Claude, a new feature on its browser extension that lets Claude use your credentials but blocks your private info from reaching the model, its memory or Anthropic's systems. 1Password built a "zero-exposure security framework" that allows agents to use stored credentials from your 1Password vault without them reaching the model. Access is granted per session, limited to specific, approved items and not carried over. Passwords and one-time MFA codes are injected through a secure channel managed by 1Password. 1Password also introduced a new Agentic Mode for all 1Password users that safeguards credentials against active agents. This will only work with Claude at first, but will expand to other agents "as the ecosystem grows." 1Password for Claude is now available to 1Password users on Mac for business, family and individual plans. Getting started requires the 1Password desktop app and browser extensions, plus the Claude desktop app and browser extensions. "Future support for payment cards and identity details will be available after launch," according to 1Password.
