# Sync cookies

> Copy your existing local browser logins into a cloud profile. No passwords, no re-login.

Already logged into the sites you want to automate? Sync those logins from your own browser into a cloud **profile** — you get a `browser_profile_id` with all that state, and never send a password.

## Sync in one command

```bash theme={null}
export BROWSER_USE_API_KEY=$BROWSER_USE_API_KEY && curl -fsSL https://browser-use.com/profile.sh | sh
```

This opens a browser where you pick which accounts to sync. When it finishes you get a `browser_profile_id`.

## Use the synced profile

Pass the id into any run to start already logged in.

<CodeGroup>
  ```python Python theme={null}
  from browser_use import BrowserUse

  client = BrowserUse()
  run = client.agents.browser_use.run(
      task="Check my LinkedIn messages and summarize them",
      browser_profile_id="bp_your_synced_id",
  )
  print(run.output)
  ```

  ```typescript TypeScript theme={null}
  import { BrowserUse } from "browser-use";

  const client = new BrowserUse();
  const run = await client.agents.browserUse.run({
    task: "Check my LinkedIn messages and summarize them",
    browser_profile_id: "bp_your_synced_id",
  });
  console.log(run.output);
  ```

  ```bash curl theme={null}
  curl -X POST https://api.browser-use.com/api/v1/agents/browser-use/runs \
    -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{"task": "Check my LinkedIn messages", "browser_profile_id": "bp_your_synced_id"}'
  ```

## Sync vs. agent login

|                  | Sync cookies                     | [Agent logs in](/cloud/browser/authentication) |
| ---------------- | -------------------------------- | ---------------------------------------------- |
| Credentials sent | none — reuses your local session | agent uses credentials you provide             |
| Best for         | sites you're already logged into | fresh logins, headless setups                  |
| Setup            | run `profile.sh` once            | one login run                                  |

Both produce a `browser_profile_id` you reuse on every run.
