## Can Chat4Data scrape data behind a login?

Yes. Chat4Data can scrape password-protected websites.

<Steps>
  <Step title="Log in manually">
    Open the website in your browser and sign in with your credentials as you normally would.
  </Step>

  <Step title="Start Chat4Data">
    Open the extension while you're on the authenticated page. Chat4Data operates within your existing session.

## How does Chat4Data handle anti-bot protection?

Chat4Data stays undetected by acting like a real human user. Instead of aggressive bot-like scraping that triggers rate limits or blocks, the AI mimics natural browsing patterns:

* Human-like click and scroll timing
* Natural pauses between actions
* No rapid-fire requests

This approach bypasses most anti-bot systems automatically.

<Info>
  For rare CAPTCHA challenges, AI-powered CAPTCHA handling is currently being rolled out to resolve these seamlessly in the background.

## What are the dynamic interaction capabilities? *(v3.0.0+)*

Starting with version 3.0.0, Chat4Data supports complex, interactive workflows:

* **Multi-region extraction** — pull data from different areas of a page in a single run
* **Dynamic interactions** — clicking buttons, applying filters, typing into search fields
* **Human-in-the-loop** — Chat4Data can pause and ask you to complete a login or verification step, then resume automatically
* **Flexible page exploration** — not limited to fixed scraping workflows
