Ask a question and very kind Alvaro has answered, only that I do not understand codes and I do not know how to integrate with path's the question and answer was this:
If I have 2 htaccess files in different directories? Do I need to create 2 htpasswd or 1 htpasswd does it work for both?
A single htpasswd would be good for both. The only thing is that you may have to define different path's in each htaccess file. But both can use it without problems (example: it could be the case that you have different protected areas within your website but users / passwords are common in both).
I will appreciate information step by step, thank you. (is to make my page safe)
