sr06 Hi, so once you enable 2FA the QR code appears, and you then need to use a mobile device to scan over the QR code.
You need to make sure before you scan the QR code that you already have a authentication app (e.g. Google authenticator) installed. This allows you to set up 2FA via the authentication app and receive the verification token, which you then add to the Ezoic dashboard.
Here's our guide if necessary: https://support.ezoic.com/kb/article/how-do-i-enable-twofactor-authentication
