Digital-ID (Aadhar) was heavily pushed by USAID and other US-deepstate associates; the same with digital-money and the "demonetization". Bill Gates's org actively tests out things on actual humans like guinea pigs, before globalizing the "solutions". These days all of this is kind of redundant since the phone-number + verification has become essentially a necessity to live in the city in any part of world today.
The prev. Govt. had considered doing this "login with your ID or no internet" scheme (to "protect" people no doubt) back in 2012s - there were explicit statements about disallowing people who would not authenticate with Aadhar, but it was shelved (likely because of their unpopularity).
If our current "Dear Leader" were to propose this, I think a significant population would opt-in simply because of a sense of belonging to a hero-worship-cult.
The state is determined to ensure that every human be their slave.
