WordPress User Registration Without Password Requirement

In a previous tutorial, we learned how to build a WordPress user registration form without username field. Sequel to that, we will be learning how to create a (front-end) registration form without a password field. That is, users won’t be required to supply a password before they are registered. Process Overview
When a ProfilePress powered registration form do not include a password field is used to register users to a WordPress powered site, a password reset message is automatically sent to the user on successful completion of the registration process.
You could decide to disable the password reset email that is sent immediately after registration and instead, include the link for the user to reset their password in a crafted welcome email delivered to their email.
Building the Registration Form
I assume you have ProfilePress installed and activated as well as the Memories Registration Form theme. If not, do that now.
Navigate to ProfilePress >> Registration Form, click the title of Memories Registration Form to open the edit screen.
Replace the content of Registration Design with the code below and save your changes.
