02
Use QR setup, live TOTP confirmation, and recovery codes without extra friction.
KeepCipher shows the QR code, accepts authenticator verification, and issues recovery codes so protected archives stay usable even when the primary device is unavailable.
03
Generate a Pro activation code instantly.
Generate your activation code first, use it during checkout, and then activate Pro directly inside the desktop app.
