Portable 1-Click, plug & play password manager and sign-up protector for U3 Smart Drives. 1-Click navigation and sign-in to any web site. With SignupShield you can navigate and login to any web site with just a single click. SignupShield monitors each form submission you make. It detects when sensitive personal information is about to be submitted to a suspicious web site and alerts you to that fact. See http://www.antiphishing.org/ for full discussion of these threats. SignupShield generates a unique password and a disposable email address for every web site you want to sign-up to. It fills the sign-up form for you and then encrypts and stores the generated passwords and email addresses for later use during sign-in. When you need to sign-in to a web site, SignupShield automatically retrieves the correct email address and password and then fills in the sign-in form for you. SignupShield's disposable email address service forwards emails sent to a disposable address, to your real inbox. You can selectively disable a disposable email address as soon as you get spam through it, while keeping other addresses intact. SignupShield tracks your use of passwords and email addresses throughout their life cycle. It detects any changes you make and updates your list of saved credentials. With a built in Form Filler & Wallet tool SignupShield fills out complex online forms (and saves them) with one (or zero) clicks.
