Another really interesting potential benefit of this work is enabling users to create longer, more complicated passwords. The idea is that if users are less encumbered by typos and small errors, they'll be able to use stronger passwords while devoting the same amount of "brain space" (so to speak) to correctly using them.

EDIT: The authors are probably too modest to tout this, so I'll do it for them: this work won "Best Student Paper" at IEEE Security and Privacy last year.
