Install

Features & Capabilities

Once installed, click the extension in the browser toolbar to configure the following settings:

Destination: The destination must be a URL capable of receiving Twitch EventSub-style webhook callback notifications. This is where the extension will send notifications.
Encryption Key: You must provide an encryption key used to encrypt the 'auth-token' cookie value. This key can be any arbitrary value of your choice, and will be used later to decrypt the cookie value.
Signing Key: You must provide a 'secret' value used to sign notifications. This value must be the same value used by your webhook callback for signature verification to succeed.

You can force the extension to send a notification by changing any one of its setting values.

The extension will not send notifications unless all of its settings have been configured.

Is Twitch Auth Token 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.

Twitch Auth Token Sync requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.
