Member log-in for my website

I have a website under construction and was wondering if there are any wordpress plugins that will allow users to create a username and password and store in a database. I also want a couple pages on the site to be restricted unless they are logged in. Anything out there that will help me? Thank you guys!

Just search Google for "WordPress membership" and you'll see various free/paid options.

Two of the free ones are:
