What happens if I lose my Grid and can't login?
Whenever you login with your Grid enabled, you are prompted to enter coordinates from your Grid as authentication. Underneath the entry fields for these coordinates, there is a link entitled "If you lose your grid, click here to disable grid authentication." Clicking this link will send an e-mail to your LastPass account e-mail address (or security e-mail address if you have set one), that will contain a link that will temporarily disable your Grid. If you are unable to access your e-mail for some reason, and have lost your Grid, please contact LastPass support.
