Use your FIDO2 device as a TOTP token with our Companion app

product updates

01-06-2020

TOKEN2 Companion app is a tool to leverage the use of TOKEN2 FIDO2 security keys (second-generation only, T2F2-ALU, and T2F2-NFC) beyond classic U2F and standard FIDO2/WebAuthn functionality. The app enables you to set and use TOTP profiles on a Windows machine.

As the FIDO2 security keys do not have a system clock nor a display, they cannot be used as standalone TOTP tokens. However, you can save TOTP profiles on your T2F2-ALU and T2F2-NFC security keys and retrieve the generated OTPs via the companion app. This will allow using the same device for your FIDO2 and TOTP protected accounts (i.e. use the same key for Azure Passwordless and Azure MFA login).

The FIDO2 USB Security keys are not standalone TOTP tokens:  TOTP functionality of our FIDO2 keys is limited and requires an additional device (i.e. a PC, Android phone or iPhone)  to run the companion app. The key in this case is only used as secure storage for the TOTP seeds. If you need a fully standalone TOTP token, it is recommended to use our programmable tokens instead.
