A ‘Virtual Keyboard’ allows you to help avoid your keystrokes being captured by keyloggers, since keyloggers can’t capture mouse clicks. If you are using a public or insecure computer, the Virtual Keyboard feature allows you to enter your email and Master Password without a single keystroke.
The Virtual Keyboard can only be accessed via the LastPass website, which you can navigate to directly at https://lastpass.com or by launching after being prompted to login via the LastPass plugin.
If you navigate to the site, click on the link in the upper-right hand corner to Sign In:

You can also launch the Virtual Keyboard when logging in using the LastPass browser plugin:
