 The `.htaccess` file references a `.htpasswd` file in which each line consists of a username and a password separated by a colon (`:`). You cannot see the actual passwords as they are [hashed](https://httpd.apache.org/docs/2.4/misc/password_encryptions.html) (using MD5-based hashing, in this case). Note that you can name your `.htpasswd` file differently if you like, but keep in mind this file shouldn't be accessible to anyone. (Apache is usually configured to prevent access to `.ht*` files).

 ### Restricting access with nginx and basic authentication
 
 For nginx, you will need to specify a location that you are going to protect and the `auth_basic` directive that provides the name to the password-protected area. The `auth_basic_user_file` directive then points to a `.htpasswd` file containing the encrypted user credentials, just like in the Apache example above.
 
-    location /status {
-        auth_basic           "Access to the staging site";
-        auth_basic_user_file /etc/apache2/.htpasswd;

 These novelties have not been introduced as concerted effort, but as a try-and-see approach over the 1991-1995 period: a server and a browser added one feature and it saw if it got traction. A lot of interoperability problems were common. In November 1996, in order to solve these annoyances, an informational document describing the common practices has been published, {{RFC(1945)}}. This is the definition of HTTP/1.0 and it is notable that, in the narrow sense of the term, it isn't an official standard.
