how safe is a checking account?

in addition to @mhoran_psprep answer, and inspired by @wayne's comment.  if the bank won't let you block automatic transfers between accounts, drop the bank like a hot potato they've utterly failed basic account security principles, and shouldn't be trusted with anyone's money. it's not the bank's money, and you're the only one that can authorize any kind of transfer out.  i limit possible losses through debit and credit cards very simply. i keep only a small amount on each (~$500), and manually transfer more on an as needed basis. because there is no automatic transfers to these cards, i can't lose everything in the checking account, even temporarily.
