Yes, and it depends on what you want.

For example:

You can set PAM to require a TOTP: 
libpam-google-authenticator
libpam-oath
which can be required on all logins or on all SSH logins.

There are some fingerprint readers that can be plugged in to PAM
for local logins.

Tell us more about your threat model.
