hidden backend breaks password-reset mails

I hava a hidden backend, with ithemes-security and was just about to launch my user-area until I found out, the password-reset feature is broken. As described in this post https://www.ads-software.com/support/topic/reset_pass_link-issue-with-itheme-security/.

Has anyone solved this problem?
I tried the shortcode from the Template Tags-Box on the right [reset_pass_url] which gets printed as plain text. Only [reset_url] that is not inside the box but included in the default-templates toes the trick to send out a password-email. However it gets it’s parameters confused.
