Security codes are used to ensure that a communication partner is human and not a robot. Common use cases for security validations (often specified as CAPTCHAs) are web based applications that could be manipulated or abused by robots, e.g. online queries and login dialogs. Image 1 on the left shows an example for a security validation of the KUKA Exchange Portal login dialog. In this case the string "kb93m" consisting of characters and numbers has to be entered to successfully validate the security code. Image 2 shows the input box needed for the secuirty code validation that can be found in the login form.

All security codes consist of numbers and characters and have to be entered without blanks or special characters.
