Hand somebody a password without leaving it in a chat window. The text is

encrypted in this browser and the key travels in the link, never to the

server - so nobody here can read what you send, including an administrator.

This browser cannot encrypt in page (Web Crypto is unavailable, which

usually means the site is not being served over HTTPS). Secure send needs

it, because the whole point is that the server never sees your text.
