Is there such thing as Tekkit client offline?

Hello, I need help with my mod stuff, i wanto use tekkit from technic pack but i only have a cracked account, and cracked account cant go on anymore. Does anyone have a Tekkit client that's only offline mode and no need to login to play? If there's no such thing can someone teach me how to use a mod? Please help out here

Check out the minecraft hacks section and get the cracked technic launcher, then just get a free mc account and login with it.
