It's time to change your Gmail password

Around 5 million Gmail usernames and associated passwords were leaked on a Russian Internet forum on Tuesday.

Thankfully, less than 2 percent of real, current username and password combinations, or about 100,000, were released, Google's Spam & Abuse Team wrote in a blog post. Many are old and many don't match -- for example, the user name is for Gmail, but the password is for Facebook.

If your current Gmail password and username were compromised, Gmail would have let you know by now.

if you doubt about your Gmail account security please change your Gmail account password and activate 2-Step Verification.
