Note: The prompts changes to reflect the current mode.

router#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
router(config)#line con 0

Configure the password, and enable password checking at login.

router(config-line)#password techpass0
Exit configuration mode.

Note: Do not save configuration changes to line con 0 until your ability to log in has been verified.
