1. Sign In: The Sign-In button is your gateway to Azure B2C, which provides a seamless and secure authentication experience across many GfK Applications.
   After clicking this button, your identity is verified with the Single Sign-On security features of Azure B2C.
2. Proxy Login: To login as a proxy user, you have to enter =proxyusername@gfk.proxy in the login screen.
   To use the proxy login functionality, you must own the CS-Role of the requested client.
3. Sign Out: The Sign-Out button will log you out of the StarTrack Portal.
4. Sign out from all GfK applications: This will log you out of StarTrack Portal and other GfK Applications.
   The Single Sign-On session ends. This is required if you want to use a proxy or alias login.

Important:
For security reasons, the new StarTrack Portal does not support the old SSO technology.
The new solution - federating Active Directories - replaces the old Gateway account access and is implemented by all clients, who used the old solution before.
This empowers clients with a unified authentication experience, enabling Single Sign-On across diverse applications and platforms.
This not only enhances user convenience but also bolsters security by leveraging centralized authentication mechanisms and ensuring consistent access policies.
