Hi Alan,

this is why you should pick a solution like privacyIDEA where you can
choose amongst or combine different authentication devices like the
smartphone and OTP cards, which fit into the wallet or even devices
where you can generate the secret key on yourself like the Yubikey or
the eToken NG OTP.

Thus you can decide which is the most reliable authenticator in this

Kind regards
