On your primary authentication server (even one that is offline), run:

bfpass-cli init --output /etc/bfpass/master.salt

While BFPass is a general protocol, it excels in specific niches. On your primary authentication server (even one that

BFPass replaces traditional text passwords with a live facial map. The process typically involves: Keep this salt safe

Smart factories with legacy IoT sensors often lack robust onboard compute. A bfpass string embedded in a firmware update packet allows the sensor to bypass its standard read-only memory (ROM) protections temporarily to accept a patch. Once the update is complete, the BFPass self-destructs.

Mobile apps that need to function in subway tunnels or remote areas can cache BFPass credentials. The app can authenticate the user against locally stored rules without pinging a home server until connectivity is restored.
