The vast, vast majority of scams target human behaviour, not 2FA/MFA devices and their backend systems. Actual penetration of a system due to compromising a 2FA/MFA is unheard of.
Modern MFA is based on 3 types of criteria. It checks for something you know (password, pin etc), something you have (dongles, smartphone, access to an email account) and something you are (biometrics; fingerprint, voice etc). Your 1920's dongle doesn't provide modern MFA security.
But hey, if you have faith in your random number fob, cool. Faith can be a powerful thing. Just ask a Scientologist.
