Several high-profile companies recently reported that user passwords had been stolen from their sites. If you use these sites you should login and change your password. Even if you don’t use these sites, it’s a good idea to regularly change your passwords.
Here are more ways to protect your accounts:
Don’t use the same passwords for every site. Cybercriminals steal passwords on websites that have weak security, and then they use that same password and user name in more secure environments, such as banking websites.
Go directly to a website to change your password. Emails that include links to change your password or ask you send password information by email to confirm your account could be fraudulent. To change your password, use your favorite links or enter the URL directly into your browser.
