The validator coordinator can ‘reset’ the passwords of the administrator users of the authorities for which it is validator, but not those of the other users (those who are not administrators) since no one (not even the validator coordinator) can know the internal structure of another authority (which users form it, whether or not it uses allocation, etc. ). Non-admin users should therefore contact the administrator of their authority (after all it is ‘closer’ to them) for a reset of their password. Only if the administrators themselves have forgotten their password can they contact their coordinator to restart it.
