Sharing with people who do not have a Prezi account

Hi everybody,

I am pretty sure that this question is a basic one but I would like to know if it is actually possible to share your Prezi with people who do not have a Prezi account but by sending a link to their email addresses. Because most of the people won’t take the time to create a new account just to have access to my presentation.
I would also like to know if I could lock it with a password to make it safer. (Do I need to pay for a package, If i want to get this option.

Thank you.
