The reader, who did not want to be named, said the hacker broke in and changed his password, locking him out of his account. We found several cases of people saying their OkCupid account had been hacked. “It was two days of constant damage control until [OkCupid] finally reset the password for me.” Other users we spoke to had better luck than others in getting their accounts back. There has been no increase in account takeovers on OkCupid.” Even on OkCupid’s own support pages, the company says that account takeovers often happen because someone has an account owner’s login information. “If you use the same password on several different sites or services, then your accounts on all of them have the potential to be taken over if one site has a security breach,” says the support page. When asked how OkCupid plans to prevent account hacks in the future, the spokesperson said the company had “no further comment.” In fact, when we checked, OkCupid was just one of many major dating sites — like Match, PlentyOfFish, Zoosk, Badoo, JDate, and eHarmony — that didn’t use two-factor authentication at all.
