So long as you keep your password a secret, and be sure not to leave yourself logged in at public computers, no one should be able to get into and use your account.

I cannot recall a case of somebody actually hacking another users account - though people often use it as an idle threat when they've been banned or are not getting their own way. Unless your password is stupidly easy, you should be fine.
