|
// Interfaces to the cAuthenticator class representing the thread that authenticates users against the official Mojang servers
|
|
// Authentication prevents "hackers" from joining with an arbitrary username (possibly impersonating the server admins)
|
|
// For more info, see http://wiki.vg/Session
|
|
// In Cuberite, authentication is implemented as a single thread that receives queued auth requests and dispatches them one by one.
