Simple question...I've noticed several large sites (Facebook, Twitter, etc) have ditched the idea of requiring new registrants to confirm their new password by typing it again.
Balancing usability and error-prevention effectiveness...is it better to require confirmation or not?
I would say yes, it is a useful feature.
I've mistyped a new password on multiple occasions, and I'm glad the software caught it then, rather than later, since resetting or changing a password later is generally a cumbersome process (relative to just notifying me right then that it was wrong).
