How to redo yii2-advanced authorization?

Question

Yii

It is necessary to redo the authorization. More specifically:
The database should have fields: id username number created_at updated_at
the rest is not needed.
I started to edit a bunch of errors, is there a shorter way?
and is it possible to delete the user model and everything connected with it at all? And write it again.
Or is there another solution?
