This will generally give better performance because it avoids the expense of reading distributed configuration files. If you have this option, this method is recommended.

If you do not have the ability to modify the virtual host file or if you are already using. Apache uses. The disadvantage is that Apache has to re-read these files on every request that involves the directory, which can impact performance. Begin by opening up the virtual host file that you wish to add a restriction to. Authentication is done on a per-directory basis. Within this directory block, specify that we wish to set up Basic authentication. For the AuthName , choose a realm name that will be displayed to the user when prompting for credentials.

Use the AuthUserFile directive to point Apache to the password file we created. Finally, we will require a valid-user to access this resource, which means anyone who can verify their identity with a password will be allowed in:. Save and close the file when you are finished. Restart Apache to implement your password policy:. If you wish to set up password protection using. Turn on. Next, we need to add an.

If you enter the correct credentials, you will be allowed to access the content. You should now have everything you need to set up basic authentication for your site. On the Windows platform, passwords encrypted with htpasswd are limited to no more than characters in length. Longer passwords will be truncated to characters. The MD5 algorithm used by htpasswd is specific to the Apache software; passwords encrypted using it will not be usable with other Web servers.

Usernames are limited to bytes and may not include the character :. The cost of computing a bcrypt password hash value increases with the number of rounds specified by the -C option. The apr-util library enforces a maximum number of rounds of 17 in version 1. Copyright The Apache Software Foundation. Licensed under the Apache License, Version 2. Options -b Use batch mode; i. This option should be used with extreme care, since the password is clearly visible on the command line.

For script use see the -i option. Available in 2. If passwdfile already exists, it is rewritten and truncated. This option cannot be combined with the -n option. This is useful for generating password records acceptable to Apache for inclusion in non-text data stores. This option changes the syntax of the command line, since the passwdfile argument usually the first one is omitted. It cannot be combined with the -c option. This is the default since version 2.

This is currently considered to be very secure. We can see the db file content that there are two columns which are delimited with the :. The first column contains the user name which is ismail, ahmet, ali in this case, and the second column stores passwords in an encrypted version. We can change the existing user password we just need to provide the user name again like creating from scratch.

This will ask us the user password again. In this example, we will change the password of ismail. As we can see from out that we have successfully update the password of ismail. If we want to prevent users from access we should remove users from our database. We will use -D option and specify the user name we want to remove.
