So you have a Yahoo account. What now?

At least 500 million Yahoo users were hacked in late 2014, the company confirmed Thursday.

Email addresses, phone numbers, birth dates, passwords, security questions and answers may have been stolen “by what it believes is a state-sponsored actor,” Yahoo said.

So what does that mean for you?

If your account was hacked: Yahoo will email you this message to let you know. Change your password and security questions.

If you have a Yahoo account: Change your password and security questions. Do not click on links or download attachments in emails asking for personal information.

If you use your Yahoo password and security information on other sites: Change your password and security questions.

For BellSouth email users: Although Yahoo took over the domain years ago, the company hasn’t said if those users are included in the hack. To be on the safe side, change your password and security questions.

The company said financial information wasn’t stolen, but Yahoo users should check their credit scores for suspicious new accounts.

Here’s the company’s page for frequently asked questions on the hack.
