Step 1: Log into your cPanel and go to "Password Protect Directories" under "Security" [type 'password' into the find box to make this easier].
Step 2: You may see a pop-up asking you to choose a directory to open and, if so, choose "Web Root" and hit "Go".
Step 3: You should land in your public_html folder [document root] and you will want to click on "Up One Level" to go to your home directory.
Step 4: You will now see a list of your files in your home directory and you will see the "Current Folder" is "/". Click on the "/" [not the folder icon, but just the slash] to begin editing your wp-login.php usernames and passwords.
Step 5: Next you will see the settings for your wp-login.php protection, you will not want to modify any of the options in the "Security Settings" box or you will break the wp-login.php protection requiring manual repair.
Step 6: You can add new users via the "Create User" section and remove them via the "Authorized Users" section. To change a user's password you will first need to remove it from the "Authorized Users" section and then add it back via the "Create User" section.
