secunet protect4use offers an easy-to-use, intuitive user interface. It standardises the use and processing of a variety of tokens. It is automatically launched when necessary and terminated afterwards, making it transparent for users when it is required to perform an action. The client installed on their device provides the user with a secure means of authenticating themselves with online services such as web portals, web services or cloud applications. During the login procedure, the protect4use client creates authentication data and sends it in encrypted form to the protect4use server. The user is then authenticated on the server. If this is successful, the necessary information is sent to the web portal and the user is logged in.
