Basic access authentication

Basic access authentication is a way to make sure that only people who should have access to something have access to it. It's like a password that you use to unlock a door and make sure that only the people who know the password can get in. With basic access authentication, when you try to access a website, you have to enter a username and password. The website checks to make sure the username and password match the ones it has on file. If it does, then you are allowed in, but if it doesn't, then you can't access the website.
