About Seedkeeper PRO 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

• Add accounts by QR code scan or manual entry
• Instant search across your accounts
