I implemented TOTP as a command line app doing lookup and generation by pulling secrets from a locally encrypted password file.
And before someone asks, the decrypt key is only stored in my head and the app fails silently after a significant delay if the decrypt fails.
What I don't get is how HOTP is anything but a fail waiting to happen if used across an unreliable network. Maybe this explains why I have yet to encounter a real world deployment of HOTP.
