Definitely! VHX speeds up the purchase process by letting you set a password later and in the meantime using email links as a substitute sign in method.
To set a password, you will need to go to the overall VHX "Settings" page (http://vhx.tv/settings). We just added a shortcut link to the footer at the bottom of all of the Ultiworld VHX pages.
You may need to re-login with another email link to access "Settings", but once you do you should see a page that has fields for creating and/or changing your password. There are also other account settings there, including billing information and history.
Your account can also be used to sign in on the iOS, Android, and Roku VHX apps as well as make purchases on other VHX-powered sites.
