Authenticate to websites with human-in-the-loop browser handoff. Use when user needs to log into a website, complete 2FA, or solve CAPTCHAs for agent access.

Core Features & Use Cases

Human-in-the-loop authentication: Open a browser window for the user to complete login steps.
Session persistence: Persist authenticated sessions for reuse across agent tasks.
Error handling: Manage timeouts, CAPTCHA detections, and provider-based flows with clear results.

Quick Start

Start a session and let the user complete login in a headed browser to obtain an authenticated session.

FAQPage Schema

How do I authenticate an agent to a website that requires 2FA or CAPTCHA?▼

Web authentication uses a human-in-the-loop browser handoff to open a headed browser, letting you manually complete 2FA prompts or CAPTCHAs while the agent monitors for a successful login session.

Can I persist a browser session for reuse across multiple agent tasks?▼

Yes, web authentication uses a defined session lifecycle to persist the authenticated browser state, allowing you to reuse the active session across subsequent agent tasks without repeated manual logins.

How does human-in-the-loop browser handoff work for web login?▼

Human-in-the-loop browser handoff works by opening a visible browser window for you to complete the login steps, while the agent monitors the session state to detect successful authentication or handle timeouts.

Do I need a specific environment to handle CAPTCHA and 2FA authentication?▼

Yes, web authentication requires a browser-capable environment to open a headed browser window, which is necessary for you to interact with and solve CAPTCHA detections or complete 2FA flows manually.

What happens if a web authentication session times out or encounters a CAPTCHA?▼

Web authentication provides error handling for timeouts, CAPTCHA detections, and provider-based flows, returning clear results so you can manage failures and retry the login process if needed.

When should I use a human-in-the-loop approach for web authentication?▼

You should use human-in-the-loop web authentication when an agent needs to access a website with login flows, 2FA, or CAPTCHAs that cannot be automated and require manual user interaction to complete.
