Email authentication systems like DMARC, DKIM, and SPF can protect your domain from certain types of email threats like phishing. The authentication report allows you to view the number of messages that meet, or don’t meet, these email authentication standards.

The security dashboard also includes a summary of authentication data. For details, see Security dashboard.

Authentication graph

This graph shows messages broken down by Authenticated and Unauthenticated.

  • Authenticated—Messages that meet email authentication standards
  • Unauthenticated—Messages that don't have any email authentication

Note: You can hide lines in the graph by clicking on the legend. For example, click Authenticated to hide data related to authenticated messages. This is especially useful if one line overlaps another.

Using the drop-down menus above the graph, you also customize the graph to provide details only about certain types of messages:

To generate a spreadsheet with the graph’s data, click Export Sheet. A spreadsheet corresponding to the data in the Authentication graph will be generated and saved to your My Drive folder.

Compare current and historical data

To compare the current data to historical data, in the top right, from the Statistical analysis menu, select Percentile (not available for all Security dashboard charts). You’ll see an overlay on the chart to show the 10th, 50th, and 90th percentile of historical data (180 days for most data and 30 days for Gmail data). Then, to change the analysis, at the top right of the chart, use the menu to change the overlay line.

Authentication table

To view more details about authentication on specific dates, click any data point in the graph.

For example, by clicking the data point on August 21, a table is displayed with more details about authenticated messages on that date. The table lists the top domains that sent authenticated messages to your domain, with a message count for each domain. To view the top IPs that sent authenticated messages to your domain on that date, click IP address.
