❓ Frequently Asked Questions

Does this plugin require LearnDash?

Yes. You must have LearnDash LMS installed and active.

Is the QR secure?

Yes. The QR codes generate a short-lived, one-time token and require approval from the user’s main device before login is completed.

Can I customize the modal and design?

Yes. The plugin includes frontend CSS classes (psl-modal, psl-btn, etc.) that you can override in your theme or child theme.

Does it work with multisite?

Currently tested on single-site WordPress. Multisite support is planned.
