The User Access Toolkit (UAT) is a software add-on for LabVIEW. With this add-on, you can grant or deny access to specific functionality in a LabVIEW application, depending on the currently active user. The UAT features access limitation based on groups or feature. You can let users authenticate and log in using dialog boxes, USB dongles, or fingerprint readers. You also can combine authentications within a single configuration so that users can log in with one or more of the authentication methods. The User Access Toolkit saves your configuration data as an encrypted file.
