I think that the mention of "don't use Kwallet" in this article is confusing. Could someone clarify it or delete it if necessary. Kwallet saves your remote host login password by default. Using kwallet saves you from having to enter that password every time.
Which page are you referring to? It is usually better to create threads like this on the Talk: page associated with the page in question - that way there is a much better chance that someone will notice it.
