Important: If you think someone else is using your Google Account, change your password immediately for:
- Your Google Account (if you didn’t already change it after you noticed suspicious activity)
- Apps and sites where you use the same password you used for your Google Account
- Apps and sites that contact you through your Google Account email address
- Apps and sites where you sign in with your Google Account email address
- Apps and sites for which you’ve saved passwords in your Google Account
