Cisco Router - how to require a telnet password, but not a user name

I setup a new router yesterday and when I telnet in it is asking for a user name.
I usually require a PW, but not a user name.
This is the first time a router has not simply removed the username requirement when I set the telnet PW.

Here is the current config for the telnet PW section.
line vty 0 4
 access-class 23 in
 privilege level 15
 password 7 113C0D0C46415F1A10
 login local
 transport input telnet ssh
line vty 5 15
 access-class 23 in
 privilege level 15
 login local
 transport input telnet ssh

My other routers look like this

line vty 0 4
 password 7 03314F02575C755A5A
 login
 transport input all

How do I remove the section for line vty 5 15
and how do I remove the user name requirement for telnet - line vty 0 4

Thanks
KH

line vty 0 15
 no access-class 23 in
 no privilege level 15
 login
 transport input all

BTW, this will disable SSH.  Which is not recommended.

Just to clarify  I leave the PW line in place and then when I telnet in the router will only ask for a PW...correct?

I understand the SSH concern, but we do not use SSH on any of our routers.
