If you forget your primary password, you can still unlock your
P/PC with the reminder password. However, you cannot access
the HP security Properties tab to reset your primary
password.
If you forget your primary password, the ONLY way to reset it
is to follow these steps: 1) perform a full backup either to the
desktop PC or to a CF card using HP backup, 2) perform a full
reset on your P/PC, and then 3) restore the backup file to your
P/PC.
You can only backup to your desktop PC if you previously
saved your password when connecting with ActiveSync. If you
did not save your password, use HP backup to backup to a
CF card. For information on full backups and restores, see the
Backing up and restoring data section in chapter 9. For
information on performing a full reset, see the Full reset
section in chapter 11.
