Title:
  [MIR] libu2f-host *UDEV RULES ONLY* bin:libu2f-udev

Status in libu2f-host package in Ubuntu:
  New

Bug description:
  [Foreword]

  U2F - "universal two factor" is a recent standard to provide two
  factor authentication using elliptic curve cryptography; with physical
  confirmation; and authentication of both server and client identities.
  This is therefore stronger than the usual 6-digit codes, and more user
  friendly - just touch a button. The devices that commonly support this
  are Yubikeys among other implementations. These rely on access to
  /dev/hidraw device by the user account, which is typically otherwise
  accessible by root only. The udev rules shipped, open up, and assign
  these devices to the user seats - effectively making them "USB memory
  stick" permissions wise (a local user/seat can access it, when
  plugging it in). Previously these udev rules were shipped in
  src:systemd, but now they have been removed upstream in favor of
  maintaining them in the src:libu2f-host. On the user systems, Firefox
  / Chrome / Chromium have support to use u2f devices to authenticate
  with Google Apps, Github, Salesforce, Etc.

  This MIR is specifically about shipping the udev rules only. It is not
  about shipping the libu2f shared library that facilitates developing
  of u2f enabled apps and daemons.

  [Availability]

  Available in universe.

  [Rationale]

  All Ubuntu Desktop Flavours should be able to perform U2F
  authentication in a web-browser.

  [Security]

  udev rules only, as described in foreword, limited by vendor IDs and
  model numbers.

  [Quality assurance]

  The package is in good shape, and there is a binary package
  specifically to ship udev rules only.

  [Dependencies]

  none

  [Standards compliance]

  ok

  [Maintenance]

  At times, as more devices become available on the market, udev rules
  may need an update, and SRUs.

  seeded into desktop-common.

  [Background information]
