1. Using Google Account Settings

Google provides an easy way to see the devices where your Google account has been logged in. Once you view the devices, you can easily identify the known and unknown devices. This will help you in knowing about the Gmail login history.

  1. Open myaccount.google.com in any browser on your phone or computer.
  2. Click on Security in the left panel on PC or at the top on mobile.
  3. Then, scroll down and click on Manage all devices under the Your devices tab. Tip: You can also directly open this website to see the devices where you are signed into.
  4. You will see all kinds of devices where you are logged into your Google account.
  5. If you see a suspicious device, click on it to view more details like the services or the location where you are logged into. Please note that you cannot fully know if someone is using Gmail on the device or not. But it’s obvious that someone who has logged into your Google account from a different device can easily log in to your Gmail as both have the same password.  
  6. If you don’t recognize the device at all, click on Sign out. Please change the password after signing out of the device.

2. Using Gmail’s Activity Information (PC Only)
