I have been looking for an extension that will give us the ability to put a password on all the sites we create. We have Magento 1.8.1 and we create multiple stores under that one install. We feel having each site password protected is a plus for our customers and us. If you know of anything out there that will help us accomplish what we are trying to do please share. Thank you for your time and help on this matter.
Your question is a little confusing. What are your requirements?
You want a password on all the sites you create?
There is an option to hide your store or store views behind the login or registration form. Thus customers will get the access to the entire store only after logging in.
