Am I doing something wrong?
It is result of a set of winbuilder bugs.
Following guide and as you are already aware,
Plugin you download is at
and if you download, it is now v24
you should already see "No Password" option.
If it does not show "v24" but "v23",
it is result of one of winbuilder bug of winbuilder bugs,
click edit button on (over green small play button)
than click "source" button at top
you will see
and when you click red X button to go back to builder interface,
will show v24
winbuilder is very bugfull, and includes lots of bug workarounds even on plugin code level,
still things we develop and distribute on projects here works as intended.
