Do you use a YubiKey or the Google Authenticator app? The latter is free, and now you can use either to enable Two-Factor Authentication (2FA) here at DME Resources.
Simply log-in and choose "Edit Profile" from the Control Panel, then select your preferred method from the drop-down options for "Authentication Method".
Follow the prompts that will be shown to configure, then press the "Update" button displayed at the bottom of the page.
That was easy.
