Just add them as an administrator. If you don’t stay on as an administrator and are removed or you remove yourself, they will keep the page. Oh and no, you don’t have to share your login details. They can access the page from their own account. If they don’t have any type of Facebook account, have them set it up or you set it up.
Since you made the page yesterday, I would assume it wouldn’t make a huge difference if you started over since after 25 likes you can get a vanity URL.
