All visitors need admin credentials to access website
New person here.
I recently directed a domain (domain.com) to my website, which I host using DigitalOcean running Ubuntu WordPress on 14.04. While I was building this site, I would access it by going to the IP address (let's call it 123.456.78.90/), and then be prompted with a log-in (I would enter admin and then a password and get in fine).
Now when anyone visits domain.com, all they say is that request for the log-in credentials of the server admin. I need to make that go away so people can access my site without knowing this info. How do I do this?
