Does this config block access to the site for search robots and users?

Question

Nginx

Hello, tell me please, it is necessary to make such a config so that search robots and users who do not have a login and password can not enter the site, do I understand correctly that with such a config I achieve this goal? I just ask to make sure, otherwise maybe I'm missing something, when I go to the login request and the password crashes, the site is on modx. Thank you in advance for your response.
