You can no longer log in to your account because of this so-called disposable e-mail. 

As stated in the registration form and our terms and conditions, we do not accept accounts with one-time or disposable e-mail addresses and will delete them immediately. 

What can you do now?

You could re-register with a real email address. Please note that your old username will be blocked, so you will have to create a new one.

Without a real e-mail address, important functions such as the password reminder or password change will not work.
