Can i file my childs taxes using my turbo tax account?

does he need his own username and password

Each tax return requires a separate account with a separate username and password, but you can use the same email address for all of them. Never start another return by going back and overwriting everything in the return you just filed. This will replace your info, which means you won't be able to retrieve your return later.
