Yahoo Inc. revealed a new breach that allowed the theft of data on more than one billion users. This is in addition to the hack Yahoo! revealed earlier this year.

So Yahoo! has the distinction of allowing the two largest data breaches ever, in the very same year.

According to the company, stolen data in both cases may include your name, email address, date of birth, telephone number, and your password.

It may be time to once again to change your Yahoo! password - and the password for any accounts that use that same password.
