If you have reset it, you cannot recover it anymore.

Anyway, if it was not recognised, you need to seek help with administrator of your server.

I've tried editing the stored session for this site, thereby resetting the password, but that hasn't helped. Someone please answer me.

Actually I'm not sure what has happened but my winscp password to one of my sites isn't recognised any more, or I truly have forgotten it. How do I recover/change it?
