Remove Authentication Dialog in the browser when a particular folder is accessed

[tbt]

Hi

I am new to nginx and I want to remove the dialog box that comes up
requesting a username and password when the admin folder is accessed.
eg; http://localhost/admin

The previous developer who handled this left suddenly and left no
documentation. How can I remove this?

Thanks
tbt
