SFTP server set user/password in Apache Mina SSHD

Question

I'm using this example, taken from Java SFTP Server Library?:

public void setupSftpServer(){
    SshServer sshd = SshServer.setUpDefaultServer();
    sshd.setPort(22);
    sshd.setKeyPairProvider(new SimpleGeneratorHostKeyProvider("hostkey.ser"));

    List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<NamedFactory<UserAuth>>();
    userAuthFactories.add(new UserAuthNone.Factory());
    sshd.setUserAuthFactories(userAuthFactories);

    sshd.setCommandFactory(new ScpCommandFactory());

    List<NamedFactory<Command>> namedFactoryList = new ArrayList<NamedFactory<Command>>();
    namedFactoryList.add(new SftpSubsystem.Factory());
    sshd.setSubsystemFactories(namedFactoryList);

    try {
        sshd.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

But I need to set user login and pw for SFTP server. How can i do this? Thanks

Change new UserAuthNone.Factory() to new UserAuthPassword.Factory() and then implement and register PasswordAuthenticator object. Its authenticate method should return true for valid username and password parameters.

List<NamedFactory<UserAuth>> userAuthFactories = new ArrayList<NamedFactory<UserAuth>>();
userAuthFactories.add(new UserAuthPassword.Factory());
sshd.setUserAuthFactories(userAuthFactories);

sshd.setPasswordAuthenticator(new PasswordAuthenticator() {
    public boolean authenticate(String username, String password, ServerSession session) {
        return "tomek".equals(username) && "123".equals(password);
    }
});
