NitrokeyAuthenticator - TOTP authenticator application for Nitrokey Pro2 and
LibremKey
NitrokeyAuthenticator
Nitrokey Authenticator is a TOTP authenticator application that is compatible
with Google Authenticator. The significant difference between the two is that
Google Authenticator stores shared secret that the app uses to generate TOTP
codes is stored locally by the application. Nitrokey Authenticator does not
store the secret, but instead sends it to the USB key. It is Nitrokey Pro2, or
LibremKey, that stores the secrets for generating those secrets and it is the
USB key, that does generata those codes. Nitrokey Authenticator is only an
interface for TOTP, that is happening inside the USB key itself.
