1Password now lets Claude sign in to websites without seeing your passwords - 9to5Mac
1Password for Claude lets you authorize Claude to complete browser-based tasks that require an account login. This is useful for things like booking travel or managing online accounts.
According to 1Password, approved credentials are delivered through a secure channel and injected directly into the destination page. The password, one-time code, and other secrets never enter Claude’s context, memory, or Anthropic’s systems.
Instead of granting ongoing access to a vault, Claude requests the specific login items it needs for a task. The user can approve or deny that request with a biometric prompt, and the permission lasts only for the current session.
1Password can also broker access across multiple websites during the same task, allowing Claude to complete a multi-step workflow without stopping for a new login each time.
The launch also introduces what 1Password calls Agentic Mode.
When a compatible AI agent takes control of the browser, the 1Password extension automatically locks down the vault so that only the credentials explicitly approved for that task remain available.
It requires the 1Password desktop app and browser extension, along with the Claude desktop app and browser extension.
Support for payment cards and identity information is planned for a later update.
The Anthropic partnership was first outlined in March, when 1Password said Claude would gain consent-based access to vault items.
