About yubikey-plugin
From the official readme · v2.3Description
This is a plugin for WordPress that provides multifactor authentication with one-time passwords using the Yubikey USB token.
The plugin uses the Yubico Web service API in the authentication process.
The one-time password requirement can be enabled on a per user basis.
Installation
- Buy a Yubikey
- Create a Yubico ID & API Key
- Unzip plugin into your /wp-content/plugins/ directory.
- Enter Key ID on the Users -> Profile and Personal options page.
- Enter Yubico ID & API key on the Settings -> Yubikey options page.
Id/key confused ? Well the Key ID is the first 12 chars from the output Your Yubikey generates,
they don’t change, the Yubico ID and API Key is used when communicating with the Yubico authentication server.
