This is something I'm curious about and something I'd like to get your feedback on. Do you need to confirm passwords on sign up?
It's an extra field
For me, I don't think you do need to confirm your password. It's an extra field to fill in therefore it takes extra time to complete sign up, so the more fields there are to complete the more I'll think twice about signing up.
But what if I misspell my password?
A password field will be starred out i.e. you don't see what you're typing, which means you could easily make a mistake and submit the wrong password without knowing.
This is where the 'Forget your password' function comes in handy, which is an inconvenience but will have you up and running again with your old/new password in a couple of minutes.

What you think on Twitter
To confirm or not to confirm?
What is the best route to take if designing/developing a sign up form? Have an extra field to verify the password or forget about the extra field and assume if the user makes a mistake they can use the forgotten password link? Or is there something else about the confirm password field that I'm overlooking here?
Let me know what you think as a user and your reasoning behind your preference.
