I have facing problem when i do after LogIn the generated URL copy into another browser a user show logged in
That's because the user
is logged in. Session cookies are stored per browser (generally) and therefore another window of the same browser will share the session with the one in which they logged in. This is nothing to do with encryption or otherwise of the URL.
It is possible to stop a user using multiple windows – and even to stop them logging in twice from different browsers or different machines, if you really try. But before I give you any information about that,
why do you want to prevent the user having two views of your site up at once? Generally that is a sign of lazy coding and leads to annoying websites and it is much better to craft your site such that two windows does not cause you a problem.
