Yes!
The FTP section of the Mr.Host Customer Control Panel allows you to set up as many FTP sub-accounts on your existing account as you’d like, each with their own username and password. You can also limit the access of a new account to one of the websites under your account, so the account can only be used to modify that sites content.
The FTP section also has a feature to disable FTP access on your main Mr.Host account- for security reasons, you may want to disable FTP on your main account, and only allow access FTP access from sub-accounts. These features are handy if you want to give limited access to outside web developers.
