Mega should have a confirm password field

I had the same issue: if you try to log-in before 'confirming' your account it will give you the 'wrong credentials' error.

Steps to do: 1) log out of ANY open Mega sessions (even as a guest) 2) Click on confirmation link you received by e-mail 3) Confirm password and press button

That should get you up and running with your Mega account (not that you can use it much yet as it's still overloaded)

it does have it, once you click the activation link, you are directed to the page to confirm email & password page
