Ice Cream Sandwich (ICS) - Encryption, select different PIN than Screen Lock

Question

I was wondering if one can select different passwords for device encryption in ICS?

Having the same password for encryption and unlocking the screen isn't quite that secure...

Thanks for hints.

Answer 1

No. A quote from http://support.google.com/android/bin/answer.py?hl=en&answer=1663755:

Note that this is the same PIN or password that you use to unlock your phone without encryption, and cannot be set independently.

EDIT: I found this on xda, but I think it might be risky and not worth the effort. http://forum.xda-developers.com/showthread.php?t=1680857

Answer 2

Yes, you are able to set a different password for device encryption to the one you choose for screen unlock.

Answer 3

EncPassChanger claims to do this, haven't tested it though.
