random words. You can use some website like this, but I suggest don't use the exact list. Like maybe click a few times and pick one word from the list, click few more times again and pick one more word, click again and pick one more word and so on. Then mix the order. If you followed that method, even if the website was corrupt, they still wouldn't compromise you.
