Create a user account on checkout without email or password

Im developing a website for a customer on wordpress and he needs the user accounts to be created using first name and last name and phone only..

Which checkout the form keeps asking for email and password if we need to create a new account.. is there a way to autogenerate an email and password for the customer so he shop without any hardles?

Thank you in advance.
