RainLock v1.0 for Rainmeter

You can change your passcode by editing the skin's ini file. Change the "IfEqualValue" to whatever combination you would like. The keypad is layed out like this:

(1) (2) (3)

(4) (5) (6)

(7) (8) (9)

RainLock does not include an easy way to lock the screen but you may add the included RainLock.exe file to your startup folder to lock the screen using the keyboard shortcut Win+k.
The startup folder is located here:

"%appdata%MicrosoftWindowsStart MenuProgramsStartup"

The Lockscreen background can be changed by replacing the contents of the "LockBackground.png" with your preffered image in your screen's resolution.

Enjoy!

EDIT: Some users have run into an issue by opening the skin without checking the passcode. The default passcode is 9621. It is recommended that you change this once you begin to use the skin.

EDIT: The keyboard shortcut will only work if Rainmeter is running from "%programfiles%Rainmeter". The keyboard shortcut will be replaced with a desktop lock button in the next update.
