This is just a quick heads up for everybody who uses the /youtube/store Robot. Google slightly changed their API and as a result it is no longer possible for accounts to use the Robot with their YouTube username and password.
Instead, you will now need to enable 2-step verification and use an application specific password for the Robot's
password parameter. For the Robot's
username parameter, please use the email address of your Google account instead of your YouTube username.
We made all the necessary changes on our end to accommodate the new API requirements.
Here is a video that shows how to enable 2-step verification and application-specific passwords: http://www.youtube.com/watch?v=zMabEyrtPRg
