I believe I have found a BUG (if this is not expected behavior).
I have tried with multiple users and I always get the same result.
Changing information in the database about that user causes the password of that same user to be reset (I don’t know to what value).
I tested: Creation of a new user with a test password, logged out and login again, all working.
I entered the Editor, then in the database and opened that user, modified an information (eg “city”) after which I saved.
I tried to login again … “Wrong password”.
I think it’s a bug.
And this is absolutely not good, because we cannot risk resetting the password if we modify an information of that user in the “User” collection.
