Password Protect SmartFTP Client

My workplace is looking to get a security accreditation, and we won't get it if the auditors find that anyone can use SFTP on my PC, and can then access any server I've visited because the passwords have been saved in SFTP. IS there any way I can require users to have a username/password to get into the SFTP client?

Open the Favorites Editor then goto Menu "Favorite->Security" here you can set a passwort for your favorites.
