Do I really have to close my account when I have fraud or online takeover?

Yes, excluding debit card fraud. If your online banking has been compromised, your account information was accessible to the fraudster and must be closed to secure your account. If only your debit card was compromised, the checking account can remain open and only the debit card needs to be closed. Unauthorized checks clearing or an unauthorized ACH also means the account is compromised and must be closed.
