If you don't trust the receiver you should not be sending them anything sensitive to begin with. This feature just eliminates the messages in case something happens to the recipent or their device if either become compromised. Let's say I work IT and user Bob forgot their password again and needs a temporary reset. I can message him his temporary password that expires in 3 minutes so that they can login and set a new one.
