You need to contact your server administrator or webhosting provider. We do not know your credentials. This is a support site for WinSCP client application not of your server/webhosting.

I lost all of my password and login information. Our website was hacked and got a bug. The website server made a copy of our information and reestablished the "clean" website. However, when we tried to upload information through WinSCP after that, it did not work. This was close to a year ago. We have not tried since then and we are trying to get this portion of our website up and running again. Unfortunately, I have lost the login information and password. Can you help with this?
