This is incredibly dangerous. They say do not use this for "accounts you care about" but many people use the same or similar passwords and usernames across several sites. If you register for a site and they send you your password in plain text via email (many sites still do this) you may have just opened the door wide open for any number of hackers using brute force attacks (except they can assume the set of permutations will be MUCH smaller.) It is a cool service but if you use this you need to create a substantially different username and password to really be safe. Even if your login credentials are different someone can go through the password recovery process via email, reset it, and do whatever they want. Why would I want this to happen on ANY of my accounts? Even the ones I care least about need to be more secure than that. [EDIT] ...but maybe the people who use these services are more intelligent than the average web user, are aware of the risks, and only associate these "throw-away" email addresses with throwaway accounts.
