The Codebreaker is an item added by SecurityCraft. It can be crafted by players to gain access to Passcode-protected blocks without having to know the Passcode of the block. Right-clicking a block protected by a Passcode will instantly bypass the Passcode input screen and allow the player to activate the block or access its inventory. However, the Codebreaker only has five uses and has a 33% chance of failing to "crack" a block's Passcode successfully. This will deplete one of its uses with no benefit to the wielder. Because of this, in addition to its expensive recipe, it is recommended that players use this item sparingly.
