yea, oke I got that, but what was the thing? 2FA code? is that another term for the second password,
or is that another term for that secret sentence of maximal 255 characters?
give me please an EXAMPLE of a private key,please
because this is still very unclear to me,
I just don't understand WAT that private key is and where to find it
Your using bloockchain.info so from their site:
Two Factor Authentication
SMS Message - A Message will be sent to your mobile phone containing an authorization code required at login
Yubikey - Add a yubikey hardware USB device to an account
Email - An Email will be sent to you containing a code which must be provided at login.
Google Authenticator - Google Authenticator is a free android and iphone app which generates an authorization code to provide at login.
Those are all options you have to use as a 2nd factor. Goal is even if a "bad" guy gets password hopefully the 2nd challenge will keep it where they cannot get in.
