To change your password, simply run telnet, login to the system with your original userid and newly assigned password.
At the command prompt '$' type 'passwd'. You will then see a prompt for you old password. Please type your newly assigned password here. After you have entered your new password, you can type in you new password of your choice - twice Route once; switch many

The "passwd" command might work on Unix/Linux but the original question was in regard to a Cisco router.
If you have a line vty 0 4 password set for telnet access then you would change it in the same way that you originally set it ...
log in > enable > conf t > line vty 0 4 > password <password> > exit > exit > copy run start
The other way is to use a local authentication database ....
aaa new-model
aaa authentication login WORD local
!
username user1 password letmein
!
line vty 0 4
exec timeout 0 0
!
You can also apply this security to the console port ..
aaa new-model
aaa authentication login CONSOLE local
!
line con 0
login authentication CONSOLE
!
This will enable the local username/password database for console access.
