For such groups or pages one should now use "@nopass", not "nopass".
But indeed, many years ago the encrypted "nopass" password could be used
in such places. The snippet ensures backward compatibility for old wiki

Do you again mean that pmcrypt() is called?
PmWiki will always try to read the current page as well as the
GroupAttributes page if it exists, and check their passwords. Opening
the files from the disk will require a few milliseconds, but if no
"passwdread" attributes are present, there shouldn't be a need to call
If one requires a different authentication logic, one can define the
$AuthFunction global variable with a custom function that does the
$AuthFunction = "MyPmWikiAuth"; # replacement for PmWikiAuth()
