NOOKK FAQ

Windows 11, and macOS 14 or later. Windows 10 isn't supported.

Yes. The same NOOKK Key works on different computers, with each computer having its own NOOKK Drive.

Not at the moment — Windows and Mac NOOKK Drives use different formats and can't be moved between systems. The same NOOKK Key can still be used for a separate NOOKK Drive on each computer.

It grows as you add files. The limit is the free space on the disk where it's stored.

Currently, each computer uses one NOOKK Drive.

Yes. Unlock with another key you've added, or with your recovery phrase, then remove the lost key.

Unfortunately, your data can't be unlocked. NOOKK has no backdoor — no one, including us, can open it. Please keep your recovery phrase safe.

The key locks and must be reset before it can be used again. Resetting erases the data on the key, so it will no longer unlock your NOOKK Drive.

To fix it: unlock with another added key or your recovery phrase, then add the reset key again.

A PIN can't be recovered. The fix is the same as for too many wrong PINs: reset the key, unlock with another key or your recovery phrase, then add the key again.

The key alone isn't enough. They'd also need the computer that holds your NOOKK Drive, and your key's PIN.

Note: on Mac, if you chose not to use a PIN when creating your NOOKK Drive, anyone with both your key and your computer can unlock it — so we recommend setting a PIN. If you lose a key, remove it as soon as you can.

No. Your recovery phrase is created with your NOOKK Drive. Adding or removing keys doesn't change it, so there's no need to write it down again.

It protects against: a lost or stolen computer, someone looking through your files while you're away, and someone copying your disk to crack it offline.

It can't protect against: malware already on your computer while your NOOKK Drive is unlocked, or someone who has administrator access to your computer. Keep your system updated, and lock NOOKK when you're not using it.

Never. NOOKK support never needs your recovery phrase, your PIN, or the files in your NOOKK Drive. Anyone asking for them in our name is a scammer.

If you're ever forced to unlock, entering a separate decoy password opens a decoy drive instead of your real NOOKK Drive. Currently available on Mac only.

Files that are already saved aren't affected — just plug the key back in and unlock. Files that were being copied or transferred may be incomplete, so copy them again.

NOOKK has no main window and doesn't appear in the taskbar or Dock. Everything starts from the lock icon: in the system tray at the bottom-right on Windows, or on the right side of the menu bar on Mac.

It locks. The next time you open NOOKK, it always starts locked.

Windows: click ^ in the system tray to show hidden icons. Mac: check the right side of the menu bar.

Still missing? NOOKK isn't running — open NOOKK again.

• Make sure NOOKK is running (you can see the lock icon). Open at login is on by default — if you turned it off, open NOOKK manually after starting your computer.
• Make sure Unlock when a key is inserted is on in Settings, or click the lock icon → Unlock NOOKK Drive.

Check that you're using a NOOKK Key that's been added, that your PIN is correct, and that you touch the key while it blinks. Unplug the key, plug it back in, and try again.

On Windows, entering your PIN and touching the key happens in a Windows Security system window. That's normal.

Another app may be using the same shortcut (Windows shows a notification when this happens). Use the lock icon → Lock NOOKK Drive instead, or simply unplug your key.

An app still has a file open on your NOOKK Drive. Close that app, then click Try locking again.

You won't be told which word is wrong. Check each word's spelling and order, and use all lowercase letters.

Run the installer again, then restart your computer.
