# `Keyfob.Store.ETS`
[🔗](https://github.com/alexdont/keyfob/blob/v0.1.0/lib/keyfob/store/ets.ex#L1)

The built-in single-node store: one ETS table owned by a GenServer.

Reads (`get/1`) hit ETS directly; writes and the atomicity-sensitive
operations (`update/2`, `take/1`) serialize through the GenServer —
login traffic is low-volume, so a single serialization point is the
simplest correct design. Expired entries are treated as missing on
read and swept every `:sweep_interval_ms` (default 30s).

Add it to your supervision tree:

    children = [
      Keyfob.Store.ETS,
      ...
    ]

Single-node only: requests created on one node are invisible to
another. For clusters, implement `Keyfob.Store` over shared storage.
