I got the email below to my original gmail, recovery email, and a text by cell phone so its legit.. Also the email link leads directly to google help file on how to change your password... The email says they USED MY PASSWORD..
Someone recently used your password to try to sign in to your Google Account -
[email protected].
We prevented the sign-in attempt in case this was a hijacker trying to access your account. Please review the details of the sign-in attempt:
