I want to login too. My username is nodata. Now, I can only login to my account and look at my files because only I know my password. You can only login to your account because only you know your password. Now imagine if you could read all of _my_ files and I could read all of yours. That makes no sense. You _can_ configure that if you want, but by default we go for security. This is the same. You connect your encrypted hard disk to the system and you can look at the files on it because you know the passphrase.
