Does anyone know how to turn on BitLocker encryption on Windows Phone 8?

It's apparently supported but the details are a bit sketchy.

  • I appreciate this question is off topic for superuser-could a mod migrate it to the windows phone stackexchange site? – John Sibly Jun 4 '13 at 7:45

I spoke to a contact at Microsoft, and it turns out there is no way to simply "turn on" bitlocker encryption on the device itself. You can only do it by connecting to an external service, for which there are several options:

  • Can you expand on that last point? Does adding an Outlook.com account as an email account enable Bitlocker on the device automatically? Or is it more involved than that? If that works, it would certainly be the easiest route for a casual user to enable it. – Glass Feb 12 '13 at 21:11
  • I've not tested it yet myself - this was just what the Microsoft consultant said. If I can get hold of a device and find out I'll update the answer. – John Sibly Feb 13 '13 at 10:35
  • @Glass I've not been able to find any information on how to enable it via Outlook.com. Shame, as all the others are paid for options. – John Sibly Jun 4 '13 at 7:49

    The enterprise versions of Office 365 has a setting "Require encryption on device". See Managing Mobile Devices with Office 36 – Peter Meinl May 4 '14 at 7:51

Not sure this is on topic here but from what I have seen, Bitlocker is enabled by default on Windows Phone 8 devices. It was mentioned in some MS promo stuff I cannot seem to find. It is mentioned in this Windows Phone Security post.

"Windows Phone 8 will have device encryption throughout the entire device including the OS and its applications. Designed along the same lines as Windows 7 PCs, encryption kicks in as soon as you power up the device. This system, based off of Bitlocker (but adapted for Windows Phone)"

    This page indicates that you turn it in via an Exchange ActiveSync policy wmpoweruser.com/…, other sites say on by default. Really difficult to find a conclusive answer! – John Sibly Feb 11 '13 at 16:58

    I see what you are saying. Very confusing. I recall some early material said it would be on out of box but cannot recall if that was in a MS presentation or some written material. – Dave M Feb 11 '13 at 20:55

    It is not enabled by default. You can check if it is enabled by going to Settings --> Phone Storage. If encryption is enabled it will say "XX GB used, encrypted". If it is not encrypted, it will simply say "XX GB used". It has to be enabled via EAS policy. – Glass Feb 12 '13 at 22:00
