.htaccess - Can't figure out where the login form comes from?

Question

1C-Bitrix

Hi,
On the site in the .htaccess file, the ability to login to the admin panel is commented out.

#AuthName "Need authorization"
#AuthType Basic
#AuthUserFile /home/#/#/docs/bitrix/admin/.htpasswd
#require valid-user

However, it still remains enabled, I even tried deleting the .htaccess file and it still asked for a username and password.
Question: How can I repeat such login authorization? Or maybe someone else has experienced something similar?
When canceled it says:

"18/06/2018 09:18:07, Required User Authentication"

Answer 1

1. Open incognito or in another browser
- if opened without authorization, then just a cache
2. Try to request a static file (for example, a picture), but again incognito or in another browser
- if it asks for a password, then server settings then somewhere PHP itself asks for authorization
3. If the server settings, then .htaccess can be a level higher (folder higher), you could also put it in the hosting panel or in httpd.conf
