JordyBlommaert Would you or anybody know what the application "vortex [wsfed enabled]" is? It is not a registered application in our tenant. It has popped up for a couple of our users but they do not know what that is or what they did to cause that sign-in activity. All the other sign-in information is as expected (IP address, location, browser, OS)
Here is a sample entry from the Azure Active Directory Sign-In log:
