## What is Seedkeeper Authenticator?

Your two-factor codes should not live inside your phone.

Seedkeeper PRO Authenticator turns your Seedkeeper PRO NFC card or ring into a hardware second factor. 
TOTP secrets and FIDO2 passkeys are generated and stored inside an EAL6+ certified secure element. 
They never leave the chip: no cloud backup, no copy on the device, no account to create.

FEATURES
• Hardware-generated 2FA codes (TOTP/HOTP), displayed with a single NFC tap
• FIDO2 passkey management: list, review and delete registered credentials
• FIDO PIN setup and change from the app
• Add accounts by QR code scan or manual entry
• Instant search across your accounts
• Device information: firmware version, FIDO2 capabilities, device status
• NFC settings and advanced options
• Works with both Seedkeeper PRO card and ring

NO CLOUD, NO ACCOUNT, NO SUBSCRIPTION
No sign-up. No sync. No telemetry. The app works offline and collects no data.

OPEN SOURCE
App and firmware are published under a free software licence, so anyone can audit what runs inside your card.

DESIGNED AND MADE IN EUROPE
Built in Belgium by Satochip S.R.L. on a bank-grade secure element.

REQUIREMENTS
Requires a Seedkeeper PRO device (NFC card or ring) and an NFC-capable device.
