1Password Launches Secure Agentic Autofill with Human-in-the-Loop to Protect Credentials from AI Agents

Major AI platforms are increasingly developing browser-based intelligent agents capable of performing tasks such as browsing the web, booking tickets, and even creating music playlists. However, this evolution also introduces a significant security concern — these AI agents may inadvertently retain user credentials, creating a potential risk of data exposure.

For instance, password managers like 1Password, once unlocked, can access stored login information. This means that an AI agent could potentially retrieve and autofill usernames and passwords without additional authentication. To mitigate this risk, 1Password is now developing a new security framework specifically designed to protect against unauthorized AI agent access.

The proposed system, called Secure Agentic Autofill, introduces a human-in-the-loop safeguard: AI agents must invoke this mechanism whenever they attempt to autofill credentials, and the process requires explicit human approval before any data is transmitted. Only after this verification does 1Password allow credentials to be securely injected into the browser environment.

Here’s how the process works: when a browser-based AI agent detects the need for login credentials, it sends a request to 1Password. The system then identifies the relevant credentials and prompts the user for approval via a pop-up dialog. The user can confirm through Touch ID, PIN, or other authentication methods.

Upon approval, 1Password establishes an end-to-end encrypted channel between its browser extension and the web interface where the credentials are required. The data is then injected automatically, ensuring that the AI agent or underlying model never gains direct access to the actual username or password.

While this verification step significantly enhances security, it also introduces a trade-off — human approval interrupts the autonomous workflow of AI agents. Users must remain present to authorize credential fills, temporarily halting full automation.

Currently, 1Password Secure Agentic Autofill is available for early access through Browserbase, a platform specifically designed for AI agent browser environments and tools. This allows AI developers to experiment with the Secure Agentic Autofill feature and evaluate its balance between automation and human oversight.
