An AI agent needs your browser session, not your password

APX is a free, open-source desktop app that runs your own team of AI agents on your machine.

An agent can help with a website without turning your password into another message in a chat. The important question is not simply whether the agent can open a browser. It is who signs in, which session is used and what the agent is allowed to do afterward.

Start with a narrow task: “Open this site, let me sign in, then find the invoice. Do not send or change anything.” Check the address before entering credentials. If the site asks for a one-time code or CAPTCHA, complete it yourself rather than putting the code in the conversation or asking the agent to bypass the check.

In APX, a browser handoff lets the person take over the tab for a sensitive step and return it. That depends on the desktop browser being available: a headless server browser cannot be taken over in the same way. There are other options, including approved import of an existing login for a domain and site-scoped sign-in variables. The latter can fill an allowed field without showing the value to the agent. Neither is a reason to give every site access to a credential.

A successful login is not proof that the requested job was done. Check the account, inspect the result, and review the destination before approving a consequential action. When access is no longer needed, sign out at the site and review permissions. Removing a saved variable does not necessarily close an already open session.

The practical rule is simple: use a real handoff for the secret, then verify the outcome of the work.

Handing 2FA back to the person is the right default. A log of which domains the agent touched during the session also makes the verify step much easier afterwards.
