Does a person need a MediaZilla account to view videos or collections that I have shared?

If you are using the Share link feature as is shown below It is not necessary to create an account. When you enable the share link for a video or collection, anyone can view it via the Share URL without the need to create an account.

Note that if you are using the Deliver Digital Feature the person that receives the video, will need to create an account. Learn more about Delivery Digital Feature here.
