TOKEN2 Companion app is a tool to leverage the use of TOKEN2 FIDO2 security keys beyond standard FIDO2/WebAuthn functionality. The app enables you to set and use TOTP profiles on an iOS device, via NFC (iPhones only) or USB. The app also allows configuring FIDO settings and manage passkey records. USB via iOS (iPhone or iPad) is only supported with Release3 or newer keys.
