Apache Password Protect

Password Protect Folder Using Apache

Web designers can utilize the Apache Web Server to protect web folders. Content can be protected by a password prompt.

Content will not be accessible when a web visitor enters the wrong credentials. A user name and password will be requested every time a new browser instance is used to visit the protected content.

This tutorial uses HTML and Apache as the HTTP Server.

</html>

The HTML file contains a single paragraph inside “p” tags. This information will only be displayed when the web visitor enters the correct credentials.

.htaccess file

AuthUserFile /home/username/myfiles/.htpasswd
AuthGroupFile /dev/null
AuthName "Ojambo.com's protected content"
AuthType Basic

<Limit GET>
	Require valid-user
</Limit>

“AuthUserFile” sets the name of a text file containing the list of users and passwords for authentication. “AuthGroupFile” sets the name of a text file containing the list of user groups for authentication. “AuthName” is the authorization realm for use in HTTP authentication.

“AuthType” is the type of user authentication. “Require valid-user” will allow anyone in that is listed in the password file, and who correctly enters their password. The authentication options information was obtained from the Apache website in the tenth month of 2012.

.htpasswd file

htpasswd -c .htpasswd username

To create the .htpasswd file use the “-c” option. Additional users can be added to the same .htpasswd without the “-c” option. By default, the password file will contain the username and MD5 encrypted password.

How to Use:

Save the “htpasswd” file where it can be accessible on the web.
Attempt to access the “protected” folder in your browser.

Conclusion:

Apache can be used to protected web folders. Web folders can be accessible by approved users. The users and their passwords are stored in a file created by the htpasswd command.

The “.htaccess” file will contain the authentication options. The most important authentication information is the location of the file created by the htpasswd command. A user will not be able to access protected information without prior knowledge of the proper credentials.

Place your “.htaccess” file in the “protected” folder.
Place your “htpasswd” file in a different location from the “protected” folder.
Use encryption for the password.
