I found a good post about two-factor authentication at matt cutts blog. Two-factor authentication is something you have (e.g. a phone) and something you know (e.g. a password). It’s a Big Deal because if your account or business has two-factor authentication, those accounts are immediately less likely to be phished, hijacked, or otherwise abused.
