comment Is Steganography a safe method to store secret data?
Re-reading it it doesn't make much sense. Maybe "compress first and then encrypt, before steganography"?

comment XKCD #936: Short complex password, or long dictionary passphrase?
@kizzx2 - yes. 96^11 is smaller than 7776^6. Thus, a random password of 11 letters, chosen from 96 different characters, will be hard to use but quite good; while a random passphrase of 6 words (chosen from a list of 7776 words) will be easy to use and stronger.

comment Too many passwords?
@CamiloMartin - here's one board where battery is optional if cord is left connected (motherboards.org/files/manuals/7/ax6bc-ol-e.pdf) if the cord is disconnected you lose the RTC info but everything else is stored to EEROM. Here's an article which mentions capacitors used instead of batteries. (tomshardware.com/reviews/…) Here's a laptop that doesn't have motherboard battery (uses main battery or a capacitor) (support.apple.com/kb/TA25911?viewlocale=en_US).
