Why my wordpress site asks for http authentication?

When I upload all my wordpress site files to live using ftp. And changed the
Code:
siteurl
and
Code:
sitehome
options from the
Code:
wp_options
table. I disabled all plugins as well.

The front-end worked fine. But when I try to access wp-admin a browser popup apears asking username and password as in the picture.
There is no config for Http authentication in .htaccess file.

.htaccess content

Code:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress
