2FA process

Hi, can you please clarify how to properly set up the 2FA using an app?

In the plugin options, I see an option a checkbox for 2FA with an app, and that’s fine, but after I save the settings, nothing happens.

How can I ensure that after doing this, I’m not actually locked out? I would expect that QR codes appear after I tick this option, but nothing like that happens.

I’ve checked your documentation, but it is not clarified extensively.
