An IzzyCast Account Key is a unique key required to create IzzyCast Sessions and log into the IzzyCast Get It Page.
To get one, go to the TroikaTronix Product Page on FastSpring's online store and add an IzzyCast Account Key to your purchase the same way you would for any other purchase.
IzzyCast Account Keys are free, but when you order one, you must purchase an IzzyCast Credit Bundle along with it.
You can find the pricing information on our store and in the IzzyCast section of our Isadora 4 and IzzyCast Pricing article.
