There are 5 types of passwords that can be configured on a router.

1. enable password [enable password cisco]
2. enable secret [enable secret class]
3. telnet [line vty 0 4, password cisco, login]
4. aux [line aux 0, password cisco, login]
5. console [line con 0, password cisco, login]

They all have the same syntax/ pattern.
