TOTP Functionality bundled with FIDO2 security keys
With these key you can securely store the secrets for your TOTP profiles, using our companion app (available for iPhone, Android and Windows) to generate the OTPs.
While these keys can function as TOTP tokens through an accessory app, we strongly advise prioritizing native FIDO authentication over TOTP methods.
Unlike TOTP codes, which can be vulnerable to phishing or replay attacks, native FIDO protocols utilize the robustness of public-key cryptography, making them exceptionally resilient against such threats.
