You can import browser cookies into a Playwright headless session by transferring authenticated session cookies from your local Chromium browser, enabling immediate access to pages requiring login without manual authentication steps.

Headless browser sessions lack authentication state because they start with a clean slate. Importing cookies from your real Chromium browser solves this by transferring your existing session state into the headless environment for testing.

Yes, you can specify cookie domains directly via the command line for quick, repeatable authentication imports. Alternatively, an interactive picker UI automatically detects installed Chromium browsers to select which cookie domains to import.

This cookie import method works with local Chromium browsers, requiring the gstack browse binary and browser cookie decryption capabilities to transfer session state into the headless Playwright session for QA testing.

The best way to test authenticated staging sites is importing real browser cookies into the headless session. For example, import GitHub OAuth cookies to QA a protected staging site instantly without manually logging in through the headless browser.

No, you do not need to manually log in to test authenticated pages. By importing existing authenticated session cookies from your local Chromium browser, you can bypass manual login steps entirely in headless QA testing workflows.
