How do I get my Tableau desktop license key? To receive your Tableau desktop license key, fill out the request form found in your classroom. We will issue your license key within 48 hours of receiving your request form and you will receive your license key via your registered Udacity email address. Note: This license should only be used for the program and should not be used for commercial purposes. If you haven’t received the email with your license key and it’s been more than 48 hours, check your spam and promotion folders just in case it was accidentally sent there. After you’ve tried these options and you still can’t find your license key, please submit a request via this form so we can send you your information.
