The Vault of Secrets is a feature of Geometry Dash and Geometry Dash World. Introduced in Geometry Dash World and then in Update 2.1, it is located through the Create menu from a lock in the upper right corner, initially requiring 50 diamonds to gain access.
The Vault of Secrets contains a text field and a monster padlock button below it. Pressing the button will cycle through a series of responses and clear any input in the text field. Entering certain phrases will unlock Icon Kit rewards, secret coins, as well as any related achievements. Hints in the form of green phrases are provided every so often to help guess the codes. In the lower right corner is another door which leads to The Basement. initially requiring 200 diamonds to gain access, allowing the level The Challenge to be played than in turn allows the Basement to be accessed.
Upon entering "The Challenge", you will be given a short level to play. This level introduces a handful of 2.1 mechanics not seen anywhere else, such as the Spider and both dash orbs. Upon completing, you will be rewarded with 3 Stars, some Mana Orbs, and access to The Basement. In The Basement, there is a chest with an icon. However, after waiting a few seconds, you will see glowing eyes (as seen in the end of the trailer) behind jail bars asking for you to release him using three keys. Only one of them is available in Geometry Dash World and is obtained by opening 50 of the chests in the Treasure Room. The second and third keys are only available in the full version; the orange key is obtained from a chest in the Chamber of Time, and the blue key is a reward from the Chaos Gauntlet.
Breaking all three of the locks will reveal more of the creature in the prison. It will announce its objective to destroy Geometry Dash, thanks to the player for their efforts, and then leaves, revealing a chest behind. Noticing the commotion, the Keymaster comes down only to realise that the jail is open. The chest can then be opened, revealing an icon, death effect, and a purple key. This purple key is used to access the demon gauntlet.
Enter the codes stated as captions to unlock the respective rewards. Some rewards require additional steps to unlock.
