"Application passwords are not available" or "have been disabled"

1What causes it

WordPress Application Passwords let apps (like the wptaskify connector) authenticate without your real password. WordPress only offers them on a site served over HTTPS, and a security plugin (Wordfence, Solid Security (iThemes), All In One WP Security) or a host-level rule can switch them off. Re-enabling is safe: application passwords are scoped and revocable.

2"Not available on this site. Your site may require HTTPS"

1. Go to Settings → General. Both WordPress Address and Site Address must start with https://. Change them only if HTTPS already works for your domain.
2. If your site sits behind Cloudflare, a load balancer or a proxy, WordPress may see plain HTTP even though visitors see HTTPS. Add this to wp-config.php, above the "That's all, stop editing" line:
   if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https') { $_SERVER['HTTPS'] = 'on'; }
3. Reload Users → Profile. The Application Passwords box should now show.

3Wordfence

1. WordPress admin → Wordfence → Login Security → Settings.
2. Find "Disable WordPress application passwords" and uncheck it.
3. Save. Retry connecting.

4Solid Security (iThemes)

1. Security → Settings → Advanced / WordPress Tweaks.
2. Turn OFF "Disable Application Passwords".
3. Save and retry.

5All In One WP Security

1. WP Security → Miscellaneous (or Additional).
