I love this list but I’m not sure I agree with the idea of replacing the double password form with an option to view your password. Modt people register in a hurry to use the service and dont even care about verifying their password is correct, specially if you require numbers, special chars and min length. So, in a world where the most used passwords are ‘12345' and ‘password’, if you require a hard password, its better to verify the pass for your user cause probably he wont do it. (Maybe the try first/register later can reduce this anxiety for fast signup)
