I think I get it. Using a unique salt, they'd have to completely rebuild their entire rainbow table for each password (given a unique salt for each). Is that right? Even then, it seems like they might want to use a smaller dictionary, but rebuilding for each username would still be doable. Just slower. I totally get the slow algorithm part. Seems to me that's the trick. Our IT department is dead set against using password managers. I've been trying to learn why, given companies like lastpass use excessive salting/hashing and slow algorithms. Unfortunately, at this point, I fear my limited knowledge may actually surpass theirs. All I hear is grumbling about all my eggs being in one basket.
