1Password might just have a solution to the password security problem posed by AI agents
Secure Agentic Autofill solves common security problems with AI agents

- AI agents are being provided access to credentials in their workflows
- This can cause credentials to be fed into LLMs without user knowledge
- 1Password has created a secure solution to this problem
AI agents are becoming prolific across industries, providing employees with an easy way to automate tasks through designated workflows, but in order to function they often require credentials to access systems.
This requires human interaction to enter login details and passwords, slowing down both the AI agent and human workers. As a result, AI agents are being provided credentials through agentic browsers.
This has created a new problem has been created, especially with AI agents in headless agentic browsers, as credentials can be exposed into the underlying large-language model - but 1Password, one of the best password managers, thinks it may have come up with a solution.
Secure Agentic Autofill
1Password has developed Secure Agentic Autofill which allows AI agents to use credentials within their workflow without ever being able to see or handle the credentials themselves.
Instead, credentials are stored within the 1Password browser extension, and can be requested by an AI agent. The browser extension will fill the credentials on behalf of the AI agent, providing greater security within the workflow without impacting efficiency.
Secure Agentic Autofill uses a new protocol that uses an encrypted connection between the device and the browser extension using the Noise Framework. The password is requested by the AI agent, a human approves the credential usage, and the AI agent continues on its workflow.
1Password has partnered with Browserbase in order to deliver Secure Agentic Autofill through a new browser automation workflow UI. Just like the AI agent, the Browserbase connection has zero access to the credentials stored within the 1Password browser extension, and all requests require human approval.

Ultimately, Secure Agentic Autofill prevents credentials from being spread across agents, logs, and prompts, or distributed into areas that identity access management tools cannot see.
Additionally, by using 1Password, credentials can be better managed, added, and revoked without the fear that a password may have been leaked into the far corners of an LLM.
