Explaining the entries in the Gmail Account Information window

About Gmail Activity Information

The Gmail Activity Information (formerly known as Gmail Last Account Activity) window presents the easiest way to check for unauthorized account access or suspicious activities within Gmail. You can access this window by clicking on the Details link located below Last account activity at the bottom-right corner of the Gmail Inbox page in the standard web interface.

The window includes the last ten entries when your Gmail was accessed using web browsers, POP/IMAP email clients, Gmail or third-party mobile apps, or other Google services. It lists the IP address that accessed your email, the associated location, and the time and date. Clicking Show details next to eligible entries displays additional technical information.

All these references and details can be confusing. This post serves as a ready-reckoner that any user can refer to when verifying activity in the log.


Browser

This entry refers to access from desktop web browsers. For additional clarity, Google lists the name and version of the browser used.


POP3

This section refers to POP protocol activity under two main scenarios:

  1. Local Email Clients: Desktop clients (e.g., Microsoft Outlook, Mozilla Thunderbird, or Apple Mail) configured to access your Gmail via POP3. Connections via local clients display the IP address of your ISP or mobile network carrier.
  2. Gmail Mail Fetcher: Secondary Gmail accounts set up to fetch messages from your primary Gmail account using POP3. The fetching Gmail address is displayed for identification, and Google's IP address will be listed.

Authorized Application

This category covers four main access types:

  • Third-Party Mobile Apps: Mobile email clients such as iPhone Mail.
  • IMAP Clients: Desktop mail applications (e.g., Microsoft Outlook, Mozilla Thunderbird, Apple Mail) connected using IMAP.
  • Google App Interactions: Unreferenced entries generated when accessing internal account management settings (e.g., Manage your account) from other Google services like Google Photos.
  • External POP Fetching: Non-Google email services (e.g., Yahoo! Mail) fetching messages from Gmail over POP3. The domain of the fetching service and its server IP address are displayed.

Authorized Application ()

This entry appears with empty parenthetical brackets. Clicking "Show details" does not display additional parameters, making it distinct from standard entries.

You can consistently replicate this entry by following these steps:

  1. Log in to Gmail and click the Details link under Last Account Activity at the bottom right.
  2. In the Activity Information window, click the link labeled Visit Security Checkup for more details.
  3. Return to the Activity Information window to observe the Authorized Application () entry.

Note: This entry disappears after a few minutes and re-appears whenever the Security Checkup page is refreshed.


Mobile & Unknown Entries

Mobile

Indicates access via mobile web browsers, such as Mobile Chrome or standard default mobile browsers.

Unknown

This entry can trigger for internal session reasons. You can replicate it by signing into multiple accounts on a browser and using a secondary account to perform an action like creating a new contact. Once created, the "Unknown" entry appears in the Activity Information window of that second account. It is an internal Gmail process artifact and does not indicate a security breach.
