Two Factor Authentication

This plugin provides Two Factor Authentication (2fa) support for Known user logins.

Two factor authentication provides extra security to your known account by requiring you to provide an extra authentication code via a program on your phone (such as Google Authenticator). This means that even if someone guesses your password, they would also need to have your phone in order to enter the pin.

Installation

Install the plugin via the usual way.

The plugin must then be enabled on a user by user basis via each user's settings page. Activating two factor will generate a unique code and a QR code to scan.

Regeneration

Deactivating and reactivating 2fa will regenerate the access code, so be sure to update your authenticator account if you do this!
