Change owner state, or password of another user

I’m trying out HA, and running 0.92.0b3 nuc image in docker.

It was time add some users and fix some passwords, but it seems I am not able to modify all aspects of an already created user?

My taisto user seems to be owner, and I am trying to figure out how to change that, so that a newly created user becomes owner instead, and the taisto user is, just a user.

Additionally, I dont seem to be able to modify the password of another user, even if I am owner and admin? And owner seems to…trump admin?

And yes, I am quite a rookie in HA here.

Any pointers appreciated.
Br,
TQ

Is it really impossible to remove the owner state of a user?
