This is where you can update your website, your time zone, and set your player theme defaults, among other things.
The My Account tab is the information specific to your log in. This is where you can update your name, password, email address, and phone number.
Under Billing, you can view your plan, update your credit card, and view your invoices.
Integrations is where you can connect your Facebook account (for live streaming), and your YouTube and Vimeo accounts (for sending on demand videos).
Under Users, you can manage all of the users on your account. Please note that you can now add multiple authorized users to your account, so everyone can have their own log in!
