Questions

A physical device that proves your identity to websites without passwords. Instead of typing a password, you tap your HushKey card. The authentication happens on the chip — nothing is stored on your phone or computer.

Yes. HushKey works over NFC with iPhone (iOS 13.3+) and Android (7.0+). Hold the card near the top of your phone when prompted.
