I have just installed KeePassX, and Minikeepass on my iPhone. When I try to look at my database via Dropbox / Minikeepass, I can put in my password, but I have no option to put in my key file because in Minikeepass the key file option is set to none. I don’t seem to have any way of changing it. I have had a look in settings in Minikeepass but can’t find out how to change it. Help, this is driving me crazy.
