The session data is stored on the server. Only the session id is transferred forth and back between the client and the server. Unless a server-side script messes up (or there is a bug) the client cannot change the session data directly. But you have to ensure that only the “correct” client knows the session id, as it ties this particular client to a particular session. E.g. (since you mentioned a login) use session_regenerate_id() whenever a login (attempt) is performed to prevent session fixation
