How modify PrestaShop, to made phone-only registration?

[Awasaky]

Hello.

 

Most of my customers have only phone number, so they can't register in standart form (email based).

I need to simplify registration, because I try move to Internet my customers without email.

They need phone number only registration.

Password need to be simplified too - around 4 digits enough.

 

All another data (like name, second name, discount level etc), I want add manually, cos I have it already in my phonebook.

 

How modify PrestaShop, to made phone-only registration?

 

Thank to any suggestions.

this requires a lot of changes because almost each feature related to order process uses email to process the order, to send the notifications (like order status change), large part of modules requires email to process the payment properly, controllers to recover password. It requires complex change of many prestashop core controllers.
