Anyone who has had a Yahoo account since 2013 needs to change his user name and password ASAP! Yahoo just announced that 1 billion user accounts were hacked in 2013. What was stolen by hackers includes such personal and financial information as a user’s name, phone numbers, date of birth and even more.  All of this is information that thieves can use for a wide-range of damaging identity theft schemes.

So Yahoo account users should not — I repeat not! — wait to get the email notification that Yahoo says it’s sending to affected consumers. Sending that magnitude of emails could take more time than a Yahoo customer can safely wait. Who knows what personal and financial damage has already been done or could be done by the time the emails are sent and received.

Be pro-active and protect yourself—change your user name and password ASAP!
