What means this? ( Lua newbie )

[CTCCoco]

password ~= "" and password ~= nil

what means ~= ?

and nil?

Thanks for all.

That checks if the password is not an empty string and that it's not nil, meaning it has some sort of a value.

~= - 'not equal to'

== - 'equal to'

nil - nothing, void, no value

Maybe you should read the introduction part in the lua manual to get familiar with the language.
