Hi LumberHack, thanks for helping me out. I have made a mistake with the description of the problem.
Once Keyy is activated, a user MWP can’t login with username and password…
So MWP auto-logins with username and password. With the free version of Keyy you can only login with the Keyy app. Since you gave me a good answer, this problem is solved.
However, it would be nice if the free version of Keyy would be compatible with WPS.
Thank you
