Are you using the same password for all of your online accounts — or even the same email? That could be a big mistake when it comes to protecting your data.

Experts say we need to take our account management to the next level to keep personal information safe. Megyn Kelly TODAY consulted Caleb Barlow, the vice president of threat intelligence at IBM, and NBC News correspondent Tom Costello for some words of wisdom.

"This is one of the big challenges we all face," Barlow said. But you can take action to help protect yourself. Here's how.

  1. Keep changing your password and updating your accounts.
  2. You can check to see if you’ve been part of a data breach by using a site like this one.
  3. Don’t use the same email address that you use for watching movies as you do for your investments or your banking activities. Keep them very separate to create silos that can help protect personal data.
  4. Be leery of those personality tests you see online because they can ask too much personal information that can be used against you.
  5. When creating your online profile, don't reveal the real street you grew up on, or your mother's maiden name. Use the information of a person you know, or make up the answer with a response you will remember.

And lastly, try a password vault or manager, which can keep track of your passwords and create complex ones for your various accounts.
