Login Passkey Manager

Login Passkey Manager - Secure Credentials for Shared Devices & Privacy-Conscious Users

Perfect for businesses with shared devices and individuals who value privacy. Store WebAuthn/FIDO2 passkeys on your personal MIFARE DESFire EV3 NFC card instead of the cloud.

🏢 SOLVES REAL BUSINESS PROBLEMS
