I don't see much use for this outside the send-a-password use-case. For that it seems like one of those things that might be convenient if I need to send a password/username to a buddy but for anything at all official I don't think you will get users. Most places don't want people going out to 3rd party sites for sensitive data.

I agree that 3rd party services can be less than ideal, and sometimes really undesirable for some contexts. The reality though, is that people need to communicate these things, whether they be passwords, or tidbits of info that they don't really want to persists. The current way that they do it is via IM or email, which now get logged, stored, indexed, etc. by the client software or middle-man service providers. While we don't expect or recommend that companies put ultra sensitive data into our system (at least, not without strong encryption), we feel it does fill the more common need. We're pleasantly surprised at how many other people agree too.
