Virtual Keyboard and On Screen Keyboard, both types of keyboards may look the same, but the difference is in terms of the layout or ordering of the keys. The on-screen keyboard of an operating system uses a fixed QWERTY key layout, which can be exploited by sophisticated keylogger software. However, an online virtual keyboard randomises the key layout every time it is used, thereby making it very difficult for a keylogger software to know or record the key(s) pressed by the user.
