Yo! Sorry, yes. To sign in to the web for Backblaze B2 you can choose to have 2FV enabled - though we require that you at least set up the phone to do this. 2FV is like 2FA except in our implementation, at the moment, the only 2nd factor is a phone. 2FA tends to have a few more options (like apps and such) but it's essentially the same thing.
If so, what kind of verification is it used for?
In any case, thanks for responding here!
