Change your Google password now: Millions of Gmail accounts

Thanks, DrMark, for your quick response. I still am not sure whether "Is leaked?" means that my username and password have been leaked. After posting my message above, I looked around for more information and found an interesting news item from CBS News. Here's the part I found interesting:

Google told CBS News in an email, "The security of our users' information is a top priority for us. We have no evidence that our systems have been compromised, but whenever we become aware that accounts may have been, we take steps to help those users secure their accounts."

The company says it believes only about 2 percent of the passwords posted would have worked.

At least some users on the social media site reddit who found their usernames on the list of leaks agreed. One reddit user, rat, wrote: "This is not a Google leak but a collection of Gmail addresses with passwords from elsewhere. Based on the password hinted, I would wager this is from the Gawker leak way back when." Another user, alexander_b, wrote, "What has happened here is that crackers have aggregated passwords from other websites than Google. So if you're one of those who use the same password everywhere, you need to change your passwords right now."

So apparently the hackers have somehow gotten ahold of some usernames, but not necessarily the passwords that match those usernames. Since the passwords I use on my Gmail accounts are used nowhere else, I'm a little less worried. Still, I'm very grateful to you for posting about this, and I'll definitely be keeping an eye on any unusual activity on my Gmail accounts. Indeed, Gmail tends to notify me when someone tries to access my account from somewhere other than where Gmail expects them to be.
