[Q] Security pattern won't allow backout topic

Using cm-11-20140305-NIGHTLY on nook HD+ and went to set security pattern login.
Tried 6x6 and decided too many dots. It wouldn't let me out unless I "confirmed", but I forgot.
How can I get out. I'm considering installing the next 07 NIGHTLY.

Too late, I'm updating to 07. Now what will happen?
