Twitch Auth Token Sync is a Chrome WebExtension designed for managing Twitch authentication tokens efficiently. This free add-on facilitates the exfiltration of the 'auth-token' cookie value from Twitch whenever it changes, ensuring that users maintain seamless access to their Twitch accounts. The extension is particularly useful for developers and streamers who require real-time updates of their authentication tokens for webhook notifications.

Upon installation, users can configure essential settings through the browser toolbar, including the destination URL for webhook notifications, an encryption key for securing the 'auth-token' cookie value, and a signing key for signature verification. It is important to note that notifications will only be sent after all settings are configured, and users can manually trigger notifications by modifying any setting. For detailed instructions on usage, users can refer to the extension's homepage.
