Testing for sequences in a password, like "wert" or "asdf". Only sequences with at least 3 characters can match. So far I have:

my $password ="asdf";

if ($password =~ /(?=^asdfghjkl{3,}$)/) {
    print 'no sequences allowed!';
} else {
    print "password is okay";
}

Not sure what I'm missing.

UPDATE:
Because TMTOWTDI I decided the solution to my problem did not have to be a regexp, but could be a simple string search:

my $password ="asdf";

if (index("qwertyuiopasdfghjklzxcvbnm",lc($password)) > -1) {
...
}

This, of course, doesn't work with "asdfasdf" so still not a full solution.
