You can enable the fingerprint reader for sudo on macOS, and pressing my finger on a button beats having to type the password, steps:

1. cp /etc/pam.d/sudo_local{.template,}
2. Edit /etc/pam.d/sudo_local and uncomment auth sufficient pam_tid.so.

The reason for doing this in sudo_local is that this file will not get reset with system changes from Apple.
