cannot login using system/manager in oracle 12c Realease II database

I am trying to login to oracle sqlplus using system/manager but unable to do.

I logged in using sys user and then ran

ALTER USER SYSTEM IDENTIFIED BY manager;

It said user changed but then when I did

CONN SYSTEM/manager

It says invalid login/password.

Please tell me what I am doing wrong
