What would be more secure? What do we try to protect against?

Marek and I sat down to discuss this and feel it is keep to the same rules of the existing keyboard without modifying it just so that we can hide what we are doing. Enhancement aat most, but not defect. Perhaps we try to improve it for 2009.9.

XorA stated the obvious. When E_VIRTUAL_KEYBOARD_PASSWORD is set prediction should be turned off... and one could force the keyboard into a special mode. Only showing one char at a time...

Replying to zecke:

Sounds good to me.

Please display password characters when entering them into the Openmoko. Password security can be provided by moving the phone so others can't see it; this is much easier than using a small keyboard to enter your passphrase when you can't see if you've made any mistakes.
