It’s time to take stock of your private information.

This Sunday (Jan. 28) is Data Privacy Day, which marks the 1981 signing of Europe’s Convention 108, the first legally binding international treaty dealing with privacy and data protection. But, more important, it’s a reminder of the importance of protecting your personal data.

That’s becoming an increasingly bigger deal as the number and size of computer hacks continue to grow. In just the past year, millions of consumers have been affected by breaches at companies from Equifax to Uber, along with phishing and malware attacks on individuals.

That’s why groups such as the nonprofit National Cyber Security Alliance, a public-private partnership that promotes cybersecurity and privacy awareness, are trying to educate both businesses and regular people about the importance of data security and what they can do to protect themselves.

Every day should be data privacy day, because everything you do online has privacy implications, says Russell Schrader, NCSA’s newly appointed interim executive director.

“Whether it’s on your phone or on your laptop, whether you have a smart house or use a connected toy or stream music in the car, you’re always connected,” Schrader says.

“You always need to be thinking about your privacy—how you value it and how you protect it.”

Here are a few easy ways you can protect your privacy, along with links to further Consumer Reports resources that will help you do even more. 

Make better passwords. Great passwords go a long way toward protecting your information. Using obvious ones like, say, “password,” don’t cut it.

Long, random sets of uppercase, lowercase, and special characters are best. A password manager can help, though not all experts recommend them.

Experts also are divided on whether you should change your passwords frequently, but if there’s any chance one of yours has been stolen in a breach, change it right away.

And one other thing all experts agree on: Don’t use the same password for multiple accounts.  

Turn on 2FA. While you’re getting your passwords in shape, make sure you have multifactor authentication, or two-factor authentication (2FA), enabled. Basically, this requires you to enter a second form of identification—such as a code texted to your phone—before allowing access to your account.

These days it’s available on everything from banking websites to Gmail. And it goes a long way toward keeping the bad guys out of your stuff if your password is ever stolen.

Guard your info. Lock down your social media accounts to make sure that your posts are restricted to people you actually know. Facebook has a privacy checkup tool to help with this. And even then, think before you post. People don’t need, or want, to know everything about you.

Be aware of what’s collecting your information quietly in the background. Every time you say “Alexa” or “Hey, Google,” remember that a recording is being made. Remember that apps and websites are collecting your information, too. Keep your privacy settings for both at levels you’re comfortable with.

And if you’re no longer using an app, delete it.

Protect and educate your kids. Just because an internet-connected toy wants to know your child’s name or birthday, that doesn’t mean you have to give it to them. And think before you post something about your kids on social media. Nobody likes an oversharer, and when they’re older your children might not appreciate very personal posts about them from years before. 

On the same note, talk to your kids about smart behavior online. Just like with sex it’s never too early to have that—admittedly awkward—conversation. Pictures posted to the internet never really go away.

Run your updates. This isn’t just important for laptops and smartphones but also for your router and the “internet of things” connected to it. Known security flaws that aren’t patched give hackers easy access to your network.
