This isn’t really about the hazards of online bill pay generally, it’s about the hazards of consolidated online bill paying through your bank. I pay all my bills online, but since I do it through each company directly, there are no account switching issues. Every month I get an email with the payment due info, click the link they give me for payment, and it all goes to the right place because there is no intermediary. If I had a lot of bills I might be more tempted to use the bank, in which case this is a good reminder to pay close attention. But for now the direct pay works fine!
