Fox News Tech has some excellent advice for you if you held one of the billion Yahoo accounts that were compromised in a 2013 data breach, your name, email address, date of birth, phone number and Yahoo password and security questions have been in the hands of hackers for three years. You can certainly your risk from future data breaches by taking a few simple steps:

Don’t trust password-reset emails coming from Yahoo. Spammers and scammers will be sending out their own fake emails prompting you to reset your Yahoo password. Even if the message looks real, don’t click on any links. Go to the Yahoo FAQ page about the breach for more information, and reset your Yahoo password here.

Make sure every password on every online service you use is strong and unique. The password should be at least 14 characters long and incorporates digits, punctuation marks, and capital letters.

Turn on two-factor authentication, also known as two-step verification, on every online account that permits it. Even if a hacker has your password, he won’t get into your account unless he has your phone number as well. Setting up two-factor authentication varies from service to service, but to enable Yahoo’s, click the gear icon on the top right corner of every Yahoo page, then click Account Info at the bottom of the pop-up menu. Click Account Security in the left-hand navigation bar of the page you land on and toggle Two-Step Verification. Next you enter your mobile telephone number and choose to have Yahoo send you an SMS text message or call you. You will get a text or an automated call that will give you a PIN of at least three digits. Finally, enter the PIN into the pop-up box and click Verify.

Consider deleting your Yahoo account. As you may recall, this isn’t the first Yahoo breach that has become public. In late 2014, it was disclosed that 500 million Yahoo accounts had been hacked—the biggest hack ever at the time. In, fact there was a bigger hack the year before, the 2013 hack just revealed. Between the billion-user breach revealed Wednesday and the 500-million-user breach revealed in September, it’s pretty clear that Yahoo didn’t emphasize security. If you use Yahoo as your primary webmail provider, you might want to switch to Google’s Gmail or Microsoft’s, which both take user security seriously. Read more HERE and HERE.
