For some reason, I used email addresses as user names, which I now want to undo.
How should I go about doing that? Simply adding new users and deleting the old? I don’t think there are user specific settings, right?
Or is a user name change also possible?
I think the easiest is to add new users and remove the old ones. Can be done via the console (not tested, unsure if the quotes are necessary):
users add user1 <password> user
users add user2" <password> administrator
users remove "email1@gmail.com"
users remove "email2@gmail.com"
You can stop openhab and edit the user json db
