The Importance of JSON Cookie Files in Antidetect Browser Sessions

By Alexander Vance Published: 2026-06-23 6 min read

What Are JSON Browser Session Cookies?

Session cookies are small text files generated by web servers and stored in your web browser. Cookies record active user authentication tokens, language preferences, site interactions, and security session IDs. When exported into JSON format, these session tokens can be imported into antidetect browsers (such as AdsPower or Multilogin) to instantly restore an authenticated browser session.

Why Cookies Are Vital When Buying Verified Accounts

When you purchase a verified PayPal, Gmail, or social media account, logging in using only the username and password from a new computer signals a "new device login" to risk engines, prompting identity verification challenges. Importing the provided JSON session cookies restores the exact session state established during account creation, allowing you to bypass login password prompts entirely.
