No, you don’t. That’s your bank or maybe an Italy thing, but I can login without providing anything beyond my username and password. I do need to use an app to authorise transactions, but not for logging in and viewing my account balance or transaction history, pending transfers, etc.
A truly shocking number of people don’t use any form of adblock. I doubt that driving off the adblock users will have a significant effect on viewership (and even if it does, why would Google care, it’s not like we’re making them money).
