When did Wells Fargo Last Update
In 2000 I signed up for Wells Fargo online, after they bought my old bank. They had me create my password via phone (oh, 2000, such a simpler time). That meant my password: "password" was entered as 72779673. So any letter/number combination that translated to 72779673 would have been able to log in as me.
As some point I eventually changed my password via the online mechanism, which I assumed was a little strong, but apparently, not much so.
