I take my Nexus 7 basically everywhere, with a lot of personal and work related information on it.
Is there software that you can recommend, to lock your tablet when it gets lost or stolen? (no sim card/3g)
thanks
The software is already built-in.
1. Set your device up again, choosing "encrypt my personal data" this time.
2. Set a PIN up as your lockscreen, make it about 6-8 digits, and set the device to "lock immediately on sleep" so you need to present the PIN every time you power off the screen.
3. Install Lookout, because it'll allow you to start a search for the device and locate it every time it comes in range of a WiFi signal if it's lost or stolen (chances are you'll never see it again, but the IMPORTANT part is that your data is safely encrypted, and Lookout is free).
4. If your device is lost or stolen, change your Google password, revoke the device's password, and re-scramble your second authentication factor (you ARE using two-factor authentication, right)?
You can also install the paid version of Lookout with remote-alarm and remote-wipe so its first exposure to a WiFi signal will turn the device into a shrieking annoying nuisance with no data on it reporting its location continuously. You probably won't get it back, but at least the thief will probably smash it to little bits and think twice about stealing a Nexus 7 again.
