 "title": "Automate a logged-in workflow without giving the model your password",
 "page_title": "How to automate a logged-in workflow without giving the model your password with Stagehand",
 "summary": "Use observe to find login fields and fill them yourself, then let act drive the rest of the task.",
 "who": "Someone automating a dull task inside a web app they log into, like downloading monthly invoices.",
 "problem": "Letting an AI agent type your password means the credentials pass through the model.",
 "outcome": "A script that signs in once, keeps the session in ./browser-data and repeats the task on later runs.",
 "steps": [
  "Install Stagehand and make sure Chrome is installed locally",
  "Launch the local browser with a userDataDir such as ./browser-data so cookies persist between runs",
  "Call Stagehand.observe to find the email and password inputs, then fill them from environment variables with page.locator; observe returns real selectors, so credentials never reach the model",
  "Use Stagehand.act for steps like click the sign in button and open the billing page",
  "Run it again later: the next run starts already signed in"
 ],
 "agent_prompt": "Build a browserbase/stagehand script for <web app> that signs in using observe plus locator fill with credentials from environment variables, keeps the session in ./browser-data, then uses act to <task steps> and extract to save <data>. Never pass the password to the model.",
