• More Reliable for the enhanced features (split view, problem lists)

How to Use Cookie Login

1. Get your LeetCode Cookie (via Network → GraphQL):

   • Open the LeetCode website (leetcode.com or leetcode.cn) and make sure you are logged in
   • Press F12 to open Developer Tools
   • Go to the Network tab, filter to Fetch/XHR, then refresh the page (F5)
   • Click any graphql request in the list
   • In the right panel, under Request Headers, find the Cookie header and copy its full value

2. Login with Cookie:

   • Click Sign In in the LeetCode Explorer
   • Select LeetCode Cookie (marked as Recommended)
   • Paste the Cookie header value you copied in step 1
   • You're logged in!

Note: For leetcode.cn, follow the same steps on the Chinese site and use the copied Cookie header value. This method follows guidance similar to community tutorials CSDN blog reference.
