Hi Greatlordd,

Unfortunately our authenticator is no longer available for  '̶n̶o̶n̶'̶-̶s̶m̶a̶r̶t̶p̶h̶o̶n̶e̶s̶  J2ME based phones (Java). We currently support Android, iOS and Windows Mobile; if you don't have a phone or device with one of these, the only alternative is to use a physical authenticator instead.

Hope that helps. :)

Edited to be kinder to smart Symbian phones!
