Usually no, not as a default.
Using browser automation to scrape pages behind a login can be legitimate in some cases, but it raises more issues than scraping public pages:
- Legal/contract risk: Logins are often protected by Terms of Service, access controls, or anti-bot rules.
- Security/privacy risk: You may handle credentials, cookies, personal data, or CSRF tokens.
- Fragility: Logged-in flows change often, add MFA/CAPTCHA, expire sessions, and break automation.
- Higher detection risk: Automation is more likely to trigger rate limits or account flags.
Better approach
- Use an official API if available.
- Ask for data export or partner access.
- Use browser automation only if you have permission and no better interface exists.
- Minimize scope: only access your own account or accounts you’re authorized to use.
- Protect credentials: use secrets storage, never hardcode passwords, and avoid sharing session cookies.
- Respect site rules: rate limit, don’t bypass MFA/CAPTCHA, and don’t evade anti-bot measures.
Rule of thumb
- Public pages: prefer HTTP requests + parsing.
- Authenticated pages: browser automation only when authorized, necessary, and compliant.
If you want, I can help you choose between requests + parsing, Playwright/Selenium, or an API-based approach for your specific use case.
