NOOKK Quick Start

Lock your files behind a physical key in about 5 minutes

1

Get your computer and tools ready

NOOKK is set up on a computer. Before you begin, make sure you have:

A computer running Windows 11 or macOS 14 or laterWindows 10 isn't supported. On Windows, you'll need administrator approval once during installation.
Your NOOKK KeyIf you have a second key, keep it nearby too
Pen and paper, or your PasswordPocketFor writing down the 24-word recovery phrase you'll get in step 4
Reading this on your phone?
Setup can't be done on a phone. Send this guide to your computer:

You'll also get NOOKK software updates and security notices. Unsubscribe anytime.
Never store your recovery phrase in the cloud, in phone notes, or anywhere it could be stolen.

Download and install the NOOKK app

Download the version for your computer:

Windows 11NOOKKSetup-x64.exe
macOS 14 or laterDMG installer
Windows
1
Run the installer you downloaded
2
When Windows asks to allow changes, choose Yes — the disk driver NOOKK needs (Dokany) is installed too
3
NOOKK starts automatically and shows the welcome window
Mac
1
Open the DMG and drag NOOKK into the Applications folder
2
Open NOOKK from Applications — the welcome window appears

NOOKK has no main window and doesn't appear in the taskbar or Dock. Everything starts from the lock icon — in the system tray on Windows (click ^ if it's hidden), or on the right side of the menu bar on Mac:

Closed lock · NOOKK Drive is locked
Open lock · NOOKK Drive is unlocked
Tip: select Open at login in the welcome window, so you can unlock just by plugging in your key.
3

Create your NOOKK Drive

Click Create the first NOOKK Drive in the welcome window, or click the lock icon → Create a NOOKK Drive…

1
Plug in your NOOKK Key
2
Windows: choose where to store your NOOKK Drive (the default is fine), then click Create. A PIN is required — if your key doesn't have one yet, a Windows Security window will guide you.
Mac: click Create, then choose Use PIN (recommended) or Continue without PIN. A new PIN needs at least 4 digits; 8 is recommended.
3
When the key blinks, touch it — twice in total
On Windows, entering your PIN and touching the key happens in a Windows Security window. That's normal.
Something not working? Tap here for common causes
  • 　Can't find the lock icon: on Windows, click ^ in the system tray; on Mac, check the right side of the menu bar. Still missing? Reopen NOOKK
  • 　Windows says the disk driver can't be found: run the installer again, then restart your computer
  • 　Touch does nothing: check your PIN, touch the key while it's blinking, or unplug the key and try again
  • 　Still stuck: contact us and our team will reply as soon as possible on business days

Write down and confirm your recovery phrase (important)

You'll see 24 English words. Write them down in numbered order, then enter the 1 word you're asked for. Your NOOKK Drive is created and unlocks once it's correct.

🔑
Your recovery phrase is the only way back in if all your keys are lost Anyone who has these 24 words can open your NOOKK Drive — and no one, including us, can recover it for you.
Do
  • ✓ Write it on paper, including the numbers
  • ✓ Or save it to the Notes in your PasswordPocket
  • ✓ Keep it apart from your computer and key
Don't
  • ✕ Take a photo or screenshot
  • ✕ Store it on your computer, phone, or the cloud
  • ✕ Keep it with your key
⚠ Don't close the window before confirming. If you do, this NOOKK Drive won't be kept. (On Windows, closing once shows a warning; closing again cancels setup.)
5

Add a backup key (recommended)

Do this right after setup:

🛟
Keep two NOOKK Keys: one with you, one at home Lose one, and the other still opens your NOOKK Drive. Only have one? Get a backup key
1
Click the lock icon → Manage → Add a key, and touch your current key when asked
2
Plug in and touch the new NOOKK Key (on Mac, you may be asked to set a PIN)
3
Done — your recovery phrase stays the same, so there's no need to write it down again
✓

Your NOOKK is all set!

From now on: plug in your key and touch it to unlock — remove it to lock

▸ NOOKK support will never ask for your recovery phrase or PIN. Anyone who does is a scammer.
