You have the option to change your FTP user's password or specify particular server paths for the user. The latter requires that you have a web hosting product that allows management of multiple FTP users.
Specifying the server path is useful if you want to restrict a specific FTP user's access to a particular directory. This way, you can safely grant access to another person without them having access to your other applications.
Example: The FTP user should only be able to access the /private/ directory, which is located in the /html/ folder. Therefore, set the server path for the FTP user to "/html/private/". When the user logs in, they will be taken exclusively to the specified directory.
