Login audit log

Track user sign-in activity
If you have the legacy free edition of Google Apps, upgrade to G Suite to get this feature. 

As a Google administrator, use the Login audit log to track sign-ins to your domain. All sign-ins from web browsers are logged, including successful, unsuccessful, and suspicious attempts. Suspicious login events are shown with a red warning icon. When users sign in from a mail client or non-browser application, only suspicious attempts are logged. Sign-ins by suspended users are not logged.

  2. From the Admin console dashboard, go to Reports.

    To see Reports, you might have to click More controls at the bottom.

  3. Click Login.
  4. Optionally, at the top right, click Select columns Select columns. Select the columns you want to see or hide:
    • IP Address—Internet Protocol (IP) address used by the user to sign in.
    • Date—Date the sign-in occurred (displayed in your default time zone).
    • Login Type (SSO only)—Whether the user signed in with a Google password or via single sign-on Security Assertion Markup Language (SAML).
