can I use different passwords for boot-up decrypt and for admin?

[minesheep]

Hi,

I am going to fresh install LL.4 with full disc encryption, single boot, and I would like to confirm that I can have different passwords for
1: login FDE decrypt
2: day-to-day user/admin, authentication of updates, unlocking email client etc.

The LL manual seems to say yes, 2 separate passwords, but I'd like to be sure.

Yes you can have FDE password different that user password.

More important, the procedure for Resetting your Password, does that also apply to a FDE password?

No! if you forget your fde password you are locked out, game over.
