MELKOR: The Spanish alien is in turmoil for him.
2. Impolite? It's the opposite! A way of walking, a pronoun ... all mingled!
LORD OF THE RI
NG: Rocky?
4. Mess it up, but for something warm?
BAGGIN
S: Huge drawback to him, but it sure turns out OK!
WAT
ER: 'Tis rare in Mordor.
BA
LROG: Behold ... seize ... spin ... it's there!
8. Batman has one!
9. Sounds like a pub, or pub's speciality - this trifle of Sauron's, according to Galdor.

You need to get the theme next, really. With the exception of 9, the others won't seem to have a Tolkien connection without the theme. I was hoping Huinesoron would be around, because this password was a joke/reaction to his.
If I were to tell you:
1. You posted a password with only two clues/answers. So, for a laugh, I posted one with only one. Not to be outdone, Huinesoron posted one with zero answers.

(Go back and look).
Well, I could only beat that by going into minus figures, couldn't I?
Well, I have, sort of. You'll see when the password is solved.
2. There is another connection with Huinesoron's password. The reason 'Sauron' is one of my answers is connected to the 'Sauron' element in Huinesoron's last (or, as he put it, noughth!) clue.
