This software was initially created by Andrea Luzzardi (https://github.com/aluzzardi/pam_usb/) but is unmaintained for quite some years by now. While the years passed the community continued to work on it but there was never a centralized place merging all those improvement. The goal of this repo is to provide exactly that, resulting in an up-to-date version. See Install for installation instructions and download options for prebuilt binaries.
This repo is mainly based on community improvements from
- Pekka Helenius (https://github.com/Fincer/pam_usb) - Agent improvements and Arch packaging support
- Luka Novsak (https://github.com/luka-n/pam_usb) - UDisk2 port
- "IGP" (https://github.com/IGP/pam_usb)" (many small improvements)
- "McDope" (https://github.com/mcdope/pam_usb) (this repo),
- ... and others.

The last official release was 0.5.0 btw, some private packages used 0.6.0 to override the upstream provided version but those varied in changes from 0.5.0. This repo will be released starting from 0.7.0 when ready and includes all updates I'm aware of (Python3 port, UDisks2 support, other smaller ones) or did myself.
