Unable to Clear Quarantine- "WebSecurity" plugin

[jbost1973]

When I enter into the terminal to delete the websecurity plugin, pasting script below, it asks for password with a little key icon.  It doesn't allow me to enter a password.  I am the admin of this computer.  Where/how do I enter password?

 

sudo chflags nosappnd /Library/Internet\ Plug-Ins/WebSecurity.plugin

Just type your admin password followed by a Return key. You won't see any evidence of your typing anything during that time.
