How to change WordPress or Magento registration process?

Question

SMS

Colleagues such a question. I want to completely replace the process of registering / changing / recovering a password from email / password to PhoneNumber / SmsPassword. That is, the phone number will be an identifier, and email may not be used at all by the user during registration.
Who will tell you if there is something ready or someone has come across, or is it interesting to develop for WordPress or Magento?
