Features & Capabilities

Unofficial companion browser extension for LeetCode with Auth Sync. It is not affiliated with, endorsed by, sponsored by, or published by LeetCode.

How to use it:

Install the VS Code extension from https://marketplace.visualstudio.com/items?itemName=wilmtang.vscode-leetcode-auth-sync
Install this Firefox add-on on the same machine.
Sign in to https://leetcode.com/ in Firefox.
In VS Code, click LeetCode: Sign In and choose Auto Cookie Sync.
In this add-on popup, click Expire now, then open or refresh any leetcode.com page so the next real LeetCode request syncs cookies and browser request headers to VS Code.

How it works: the VS Code extension starts a local listener on 127.0.0.1:17899. This add-on reads your leetcode.com cookies and sends the LeetCode Cookie header to that local listener, where VS Code reuses the existing cookie login flow. Cookie values are sent only to the local VS Code listener and are not intentionally logged.

Is LeetCode VS Code Auth Sync Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

LeetCode VS Code Auth Sync requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

High Allows the extension to observe and analyze traffic in flight for the selected hosts.
Low ******* ****** ** *** ********* ******** ************* ***

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

LeetCode VS Code Auth Sync is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
