1Password has launched "1Password for Claude," a browser extension feature that lets Anthropic's AI agent use stored login credentials to carry out tasks such as booking travel or managing accounts, without those credentials ever reaching Claude, its memory or Anthropic's servers. The move addresses a growing security concern around AI agents: sharing passwords directly with a model exposes them to potential compromise if the model or its underlying systems are hacked.

The feature works via a "zero-exposure security framework" that injects passwords and one-time MFA codes through a secure 1Password channel, with access granted per session and limited to specific approved items. It also introduces "Agentic Mode" for all 1Password users, locking down credential access when an AI agent is detected and scanning pages after autofill to check nothing remains exposed. The integration is available now to Mac users on business, family and individual plans, requiring both 1Password and Claude desktop apps and extensions; it currently works only with Claude, though 1Password says other agents will be supported later, with payment card and identity support also planned.
