In WordPress, the password is mandatory for registration, so with the free version of the user registration plugin, it is impossible to exclude the password field. Still, we have auto generate password feature in the premium plan, which helps you to hide the password field on the registration form and send the auto-generated password to the user email.
According to the WordPress Support community guidelines, we can not discuss the premium features here because this support forum is for free plugin users.
If you are interested in the premium feature, please check out https://wpeverest.com. You will find the live chat option to contact our support representative.
