Open Chrome and ensure you’re signed into Chrome using the same account as your mobile device. Type “find my phone” into the search bar and hit search. The results page will include a box at the top showing you where your phone is. You can use the drop-down box to select the specific device you’re looking for, with the map showing the location. You have options to ring that phone (so you can find it at home), or recover - where you can click through and find options to lock, erase, or remove the phone from your account.
In your browser head to google.com/android/find. If you’re not logged in, log in using the same account as your Android phone. The next page opens in the Google account page to find your phone. As above, you can then select the device you want to locate that’s associated with your Google account, and ring, wipe or lock that device.
