After perfectly setting up my customizations for my device, I did a full backup using TWRP.
I also created a pin password on the device.
Later did a restore, and I was locked out!
The password no matter what I did wouldn't take.
There was also no "Forgot Password", just "Cancel".
As you can imagine, would hate to do a Wipe to Factory Defaults and start all over again.

What to do? Thank you.

ADVANCED TOPIC AHEAD!

Remove these files either with TWRP File Manager or adb:

gatekeeper.pattern.key
gatekeeper.password.key
locksettings.db

ADB commands:

adb devices
adb shell
cd /data/system
rm gatekeeper.pattern.key
rm gatekeeper.password.key
rm locksettings.db

I had this happen once and I rebooted. Cleared the error and I was able to get in.

That's true. That happened to me too, but not always.
