Android 6 used Android Open Source Project: Full Disk Encryption

Full-disk encryption uses a single key—protected with the user’s device password—to protect the whole of a device’s userdata partition. Upon boot, the user must provide their credentials before any part of the disk is accessible.

So all apps &amp; data installed on the userdata disk partition would be secured by that key. One way to think of Full Disk Encryption is like a exterior door house key, once you can get into the house, the contents are accessible.
