Password protected page Hash url

I am using owl carosel which takes a hash url to go to a specific slide (http://ift.tt/15OZLyL)

Lets say I want to visit a password protected page with the slider there (http://ift.tt/1A6nTdq)

When I visit the page I am asked for a password, upon entering it, the hash at the end is removed after the redirect. (redirects to site.com/page on success)

Any idea where I would look to keep the original url intact?

Just to confirm, there are multiple hash urls so I cannot hard code a single one.

Thanks!
