For $3.00/user/month [1] myOneLogin will allow others to sign into many applications using your password but not seeing what it is. When you want to end their access, you just delete their myOneLogin account and access is immediately removed from all programs you set them up to access. By extension, this means you can set up “single sign-on” so each person only has one password to remember. Pretty slick. There is a free trial too.
