Blocked Production Site from Search Engines - How to get it Crawled by Moz Crawler

[Modi]

I have an 'under development' site hosted, (which is an exact replica of live site as working on to add new functionalities & modules) - but its password protected, excluded from robots.txt (Disallow) & also marked noindex on all pages in the index - so that Googlebot & other Search Engines can not crawl the site

At present the development work is almost 95% completed., Now - feel like to crawl the site through SEOMOZ Roger Bot - to know the errors and all indexed urls by Rogerbot.

What's the best way to get Moz Bot crawl the site - but simultaneously continue it blocking its access to Search Engines

I have gone through - https://support.google.com/webmasters/answer/93708?hl=en, it says

a) Save it in a password-protected directory. Googlebot and other spiders won't be able to access the content-  But this way Moz will also not be able to crawl the site

b) Use a robots.txt to control access to files and directories on your server - However it also says - It's important to note that even if you use a robots.txt file to block spiders from crawling content on your site, Google could discover it in other ways and add it to our index.

c) Use a noindex meta tag to prevent content from appearing in our search results - It also says that a link to the page can still appear in their search results. Because we have to crawl your page in order to see the noindex tag, there's a small chance that Googlebot won't see and respect the noindex meta tag

Password Protected thus seems the best way to continue blocking. However, continuing with it will also block Moz bot to crawl the site. Any suggestions

Thanks
