# `PhoenixKitWeb.Users.QrLoginComplete`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v2.13.9/lib/phoenix_kit_web/users/qr_login_complete.ex#L1)

Completion endpoint for QR device-handoff login.

The desktop LiveView navigates here once its request is approved on the
phone, carrying the one-time login token. This controller exchanges that
token for the approved user's uuid (exactly once, via
`PhoenixKit.Users.QrLogin.consume/1`) and establishes the session with
PhoenixKit's own login machinery.

Keyfob's login token is single-use and short-lived, so a replayed or
stale URL lands on the login page rather than signing anyone in.
