Keep Password from being saved (mobile app)

Hi,
I am trying to add an option to delete the saved Password, so you will be asked to login once again, instead of saving the login.
I figured the best way to do this is by reseting the state of base/conference/reducer to the default state.
Do you think this is the best way? Does anyone have any clues how to go about this?
I tried it with the following in base/conference/reducer.js
export function resetPassword(){
PersistenceRegistry.register(‘features/base/conference’, DEFAULT_STATE);

}

but that didn’t really result in anything. Any pointers would be much appreciated
