if it was the welcome message, that's not a problem. It's up to you to change it. If they're emailing you your password to root after you've changed it, you might have an issue.
Considering we live in space year 3000 now, its a wonder that we still have passwords at all. Why can't we have 2 factor keypair authentication for everything? OpenID is thinking too small.
Now you are both secure and convenient.
