I'm afraid you can't. Even if you buy VideoNFTizer Multi-Chain without the Standard Version, you will not be able to login.

Here is why:

1. VideoNFTizer Standard is the main product which is either a Monthly, Yearly or One Time Subscription.

2. VideoNFTizer Multi-Chain is an Upgrade or Up-sell which adds the Multi-Chain features in your VideoNFTizer  account.

3. Since VideoNFTizer Multi-Chain is not independent, you will need to subscribe for the main product VideoNFTizer Monthly, Yearly or One Time subscription first. Else you can't login with only VideoNFTizer Multi-Chain in your account.
