I tried to use B2 recently but was being forced to enter a phone number. Waiting for a response from support, but so far that's blocking me from using B2. I don't know if C14 is better or not.
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.
