2FA or MFA for Optimizely 12 backend

Hi

Does somebody implemented a functional 2FA or MFA backend authentication in Optimizely 12?

I can find just this old post from 2019 which is not complete and not aplicable for Opti12: https://world.optimizely.com/blogs/Joshua-Folkerts/Dates/2019/2/2-factor-authentication-in-episerver/

Thanks
