Perhaps there is some ambiguity in the post from Mohammad which he could clarify. When he talks about creating user accounts I am not clear whether he is talking about creating user accounts directly on the router using the command username (I assume that this is what he intends) or whether he is talking about creating user accounts in a TACACS or Radius server and configuring aaa authentication on the cisco device. Perhaps we can get some clarification on this.
If it is user accounts directly on the router then for aaa to change his password he must have privilege level 15 and access to configuration mode. In this case he can change the password of anyone. Without access to configuration mode aaa can not change his own password.
If the user account is on a TACACS or Radius server there is usually an ability for the user to change their own password but not to change passwords for any other users.
