You can opt to receive an Account Activity Report by going to the Products tab on your Account Settings page and clicking Account Activity, or by visiting https://www.google.com/settings/activity. Once you opt in, you’ll receive an email from firstname.lastname@example.org letting you know when your new report is ready. Just click the link provided in the email to access your report. Google’s released Account Activity dashboard creates monthly reports on your usage of Google products. Depending on which products you use, you can see how many emails you’ve sent, who your most popular contacts are, what searches you’ve performed, or what computers you’ve used to sign in. Account Activity Reports are a great way to help ensure that your account is safe and to understand your use of Google products.
