Some form of TOP would make sense for us sysadmins.

Not for users and developers, though: I've had lots of trouble making
them generate PGP keys, let alone 2-factor authentication.

Develer is using pam_oath [1] for sudo, but I don't know with what
hardware. Google uses Yubikeys [1] to authenticate people in the
corporate network, but I don't know what's on the server side.
