1Password Launches Secure Agentic Autofill to Protect AI Browser Agent Logins

1Password has introduced a new security feature designed to protect user credentials when AI agents browse the web on their behalf. The company’s Secure Agentic Autofill tool ensures that sensitive login information is only provided to AI-powered browser agents when explicitly approved by the user—preventing potential data leaks that could occur if an AI system stored or misused passwords. Traditionally, 1Password’s browser extension automatically fills in passwords when users visit websites. Now, the company has adapted this functionality for AI agents powered by models like Claude, Gemini, and ChatGPT, which are increasingly being used to perform tasks such as booking travel, creating Spotify playlists, and managing online accounts. While these agents offer convenience, they pose a unique security risk: unlike humans who might forget a password, an AI agent could retain and potentially expose login details after a session ends. To address this, 1Password’s Secure Agentic Autofill works by creating a human-in-the-loop approval process. When an AI agent determines it needs login credentials, it sends a request to 1Password through the browser. 1Password then identifies the correct credentials and prompts the user for approval via a secure, authenticated method—such as Touch ID on a Mac or a passcode. Once the user confirms, the credentials are injected directly into the browser via an end-to-end encrypted channel between the AI agent’s environment and the user’s device. Crucially, the AI agent and the underlying large language model never see or store the actual password. The credentials are only passed to the browser at the moment of approved use, significantly reducing the risk of exposure. The feature is currently available in early access through Browserbase, a platform that provides a dedicated browser environment and tools specifically built for AI agents. As AI-driven automation becomes more common in daily online activities, 1Password’s solution offers a critical layer of security, ensuring that user data remains protected even when machines are doing the browsing.
