Hive could be used as an alternative and open source 2FA log in. This could be something big only hive can offer because of the free transactions.
Outsource a secure Log in to hive means for 99,9% of all internet log ins more security. Special for exchange log ins, it could be a thing.
It should be not that hard to build in ( because it would simple an log in) and would benefit a lot of apps.
For tech-heavy Fintech stuff, it could be a thing to add additional security besides the google 2FA.
What do you think about it?
