Key File

IMPORTANT This key file is required to unlock your Ultra Secure ATOM file. You need BOTH your password and this key file. Chunk Locker does not keep a copy. If either is permanently lost, the ATOM file cannot be recovered.

I understand that losing either my password or key file makes this ATOM unrecoverable.

A 256-bit key will be generated. Save it when shown; Chunk Locker does not store it.

Save This Key Now

Anyone with this recovery key can unlock the ATOM file. Store it separately and securely.

I have safely saved my key.

Password/key modes have no recovery override. No Password mode requires the Chunk Locker backend.

Max Unlock Attempts (0 = no limit)
