Configuring proxy client on terminal without leaving password on screen or in bash_history

set-proxy () { P=webproxy:1234; DU="fred"; read -p "username[$DU]:" USER; printf "%b"; UN=${USER:-$DU}; read -s -p "password:" PASS; printf "%b" "\n"; export http_proxy="http://${UN}:${PASS}@$P/"; export ftp_proxy="http://${UN}:${PASS}@$P/"; }
Prompts the user for username and password, that are then exported to http_proxy for use by wget, yum etc Default user, webproxy and port are used. Using this script prevent the cleartext user and pass being in your bash_history and on-screen
Sample Output
[bob@localhost ~]$ set-proxy
username[fred]: bob
[bob@localhost ~]$ wget
           => `index.html'

What Others Think

But doesn't that leave your password inside the environment variables? Anyone typing env can get it, then.

From my testing the environment variable is only set for the user for that session. Please correct me if you think I'm mistaken as my credentials might be exposed!
