My devices are all linked to my main Google account. This is encouraged, almost required, by Android, for example to make my Google Play apps available everywhere. However, it requires me to store my main Google password on the device, which provides access to a ton of sensitive data: all email, Drive documents, Google Wallet.
What can I do to protect myself in case one of my devices gets stolen?
The devices I currently have are Google Nexus 5 and Samsung Galaxy Note 10.1
