Login attempt failed - each time I open the companion app

Hi all,
I am wondering if I configured something wrong or if this expected behavior.

Each time I open the companion app on my iPhone, I get a “Login attempt failed” message in the log.
The history is:
I created widgets for my iPhone and complications for my Apple Watch using an administrator account on my iPhone. After finishing the administrative work, I logged off in the companion app and used my “civilian” non-admin account to log in again.
Ever since I did this, I am getting these messages.

Example:

Thanks for your help!

Addendum:
I found out that I don’t need to open the companion app to trigger an invalid login attempt. As I have widgets on the iPhone’s “desktop” (home screens) it is sufficient to unlock the iPhone to trigger such an invalid login attempt.

Funnily enough though, the widgets all seem to work.
