HTTP basic authentication will allow you to secure parts (or all) of your website with a username and password without the trouble of PHP or Javascript. This will work with any Nginx server. Installation We will be using the command htpasswd to make username and password pairs. apt install apache2-utils The apache utils include a small username-password pair encryption tool. Like the other tutorials on this site, this tutorial is for Nginx, not for Apache servers. Now think of a username and password and remember them. htpasswd -c /etc/nginx/myusers username The -c flag creates a file. You can make the path of this file anywhere outside of your webroot. Obviously the username is up to you as well. Type out your password twice to confirm. You can do this as many times as you'd like. Check out user name password pairs (the password will be securely hashed): cat /etc/nginx/myusers Nginx Config and Auth Basic From here, we are going to edit our websites config file in /etc/nginx/sites-enabled . Have in mind which folder you'd like to secure. Add something like this: server { #... location /secret-folder { auth_basic "What's the Password?" ; auth_basic_user_file /etc/nginx/myusers ; } #... } Huh? If you're stuck, try finding the line location / { Just below this block is where you should add the custom location block If you'd like to do the opposite, such as making the entire site private except for a public section, do this: server { #... auth_basic "What's the Password?" ; auth_basic_user_file /etc/nginx/myusers ; location /public/ { #... auth_basic off ; } #... } IP Addresses If passwords aren't enough we can ban an ip or accept one. location /api { #... allow 192.168.1.23: 8080 ; deny 127 .0.0.1 ; } If you want to check both a username and password with an ip address, use the satisfy directive. location /api { #... satisfy all ; allow 192.168.1.23: 8080 ; deny 127 .0.0.1 ; auth_basic "What's the Password?" ; auth_basic_user_file /etc/nginx/myusers ; } Complete Example http { server { listen 80 ; root /var/www/website ; #... location /secret-folder { satisfy all ; allow 192 .168.1.3/24 ; deny 127 .0.0.1 ; auth_basic "What's the Password?" ; auth_basic_user_file /etc/nginx/myusers ; } Now check your configuration with nginx -t Reload nginx and you're good to go!
