I don't remember having my Yahoo email used in any of Google services, but today someone just signed in using my Yahoo e-mail. I might just did use Google services with Yahoo email a long time ago.
Here's what he did to my account (according to the notifications I got in my Yahoo email):
- Signed in from somewhere using Firefox
- Changed the password of my Google Account (which uses my Yahoo email)
- Set his own Gmail address and primary username with a new/another Google account (firstname.lastname@example.org)
Now what should I do?
I tried using Google account recovery but it says "No account is found with that email address" (which is, my Yahoo e-mail).
Is it safe to change my Yahoo account? I'm afraid every activity in my Yahoo account now will be mailed to this offender. Is there a way to know what service he's using? Should I do something else?
