3. Open www.google.com/android/devicemanager from your PC or Laptop, now you can see your Zenfone is available. Where you'll now see two more options light up under the status of that device. Next to "Ring" you'll now have the new option to "Lock" as well as the old option of "Erase." Clicking on Lock will bring up a dialogue box that lets you enable a PIN or password on your phone, even if you have no security on the phone before that point.
4. If you have lost or suspect your phone was stolen, the quickest and best thing to do is immediately lock it with a strong password from the web interface (www.google.com/androiddevicemanager). Once you've assessed the situation and have found that the phone has indeed been stolen, then you may want to consider a remote wipe . Remotely wiping the device happens just as quickly as the screen lock, and erases not only the phone but also any external SDcard storage it may have. Whenever a wipe occurs you will also receive an email notification indicating where and when the device was wiped.
