Have you ever head of PrivNote? It is amazing. When you want to send someone your login, do you send the login in one email or do you send the username in one email and the password in another.
Privnote is a free web based service that allows you to send top secret notes over the internet. It’s fast, easy, and requires no password or user registration at all. Just write your note, and you’ll get a link.
Now you can send secure notes, ie, passwords, etc. that will self-destruct after being read.
