sattvasurya v0.6: WhatsApp/Phone Number Auth

With sattvasurya we are moving away from email/passwords to authing with only phone numbers. This may sound crazy especially since email is the primary mechanism for authentication for the last 30 years, but the future is becoming phone numbers for B2C communication.

While I wish Signal was the primary tool, WhatsApp is the messaging app for the world with nearly 3.9 billion users. We have to be where our customers are and the Indian community is on WhatsApp. WhatsApp is so important for Meta that the new CEO of WhatsApp is Indian.

There are many reasons for WhatsApp as a primary mechanism for outreach:

1. WhatsApp has a strong spam filtering as the API is restricted.
2. Nearly everyone uses WhatsApp so there are quite a few features available making it good for business.

Our goal is to increase the velocity of commerce and WhatsApp is the means of achieving this whatever one feels about Meta as a company.
