Is your feature request related to a problem? Please describe.

The authentication mechanism does not support a form of multi factor authentication (MFA), two factor authentication (2FA/TFA).

Describe the solution you'd like

I would really like to setup standard TOTP (or HOTP) method for two-factor authentication. I think there are plenty of suitable libraries to help with this including in Python and Javascript.

Describe alternatives you've considered

Setting it up using PAM, similar to how I use 2FA on my SSH connections (https://github.com/google/google-authenticator-libpam). Which was already suggested here: #1936. However simply implementing TOTP is much simpler and easier than implementing PAM or OS-specific authentication.
