Member Created Droplets If I Delete Member Will I Delete My Droplets

A member on my hosting account created the droplets when he moved my sites from another hosting company

I paid him to update the html on one of my websites but he put it on magenta and walked off before finishing it and he did not give me any passwords to my droplets either

So this member is no longer associated with my hosting account

Since he created the droplets can I delete him without deleting my droplets so that I can receive the emails with the passwords when I change them in order to gain access to my droplets

Otherwise the passwords will go to one of his dead emails

Thanks, Diane
