My Winphone is a Lumia 532 Dual SIM Win 8.1.
I have noticed that it is possible to access my Onedrive without any password request from the Hub Office>Places>Onedrive .
In this way, anyone who has my phone in its own hands might access my Onedrive, read, delete, edit, download my document, stored there.
The question is: How to avoid all that unless to block with a PIN code the telephon itself?
