Change password through sFTP/SSH

Change password through sFTP/SSH


I've recently set up an sFTP server using the Titan Cloud product.  I can see that suers can change their passwords throught the SITE PWD feature of FTP however I am wondering if it is possible to allow sers to change their passwords using the sFTP service?

WinSCP has an option to change the password however when I attempt it, I get access denied and the password is not changed.  I have disabled FTP as I do not require it nor want it enabled.  Do I need to have it enabld in order for this to work or is there something else I am missing?
