Did you study the protocol specification?

RFC 4252 5.2. The "none" Authentication Request

   A client may request a list of authentication 'method name' values
   that may continue by using the "none" authentication 'method name'.

As I wrote, the libssh2 API matches the protocol API closely.

Did you study the library API documentation?

/* libssh2_userauth_list
 * List authentication methods
 * Will yield successful login if "none" happens to be allowable for this user
