Perl, 33 32 24 characters
A solution in 32 characters:
$_=a;print$_++,$"until/passwore/ Not much to say about this one. I could reduce this to 27 characters if I could use newlines instead of spaces to separate the entries.
Ilmari Karonen points out that .. internally calls ++, so a better solution (25 characters) would be:
print$_,$"for a..password By taking advantage of Perl's command-line options, here's an equivalent 24-character solution:
perl -l40e 'print for a..password' The rules for counting perl flags is here, for those who aren't familiar with them.
Of course, Ilmari's 21-character solution is shorter still, but it requires a machine that can allocate an array of 120,699,639,557 strings.
