How to remove htaaccess from website

did you generate a htpasswd?
Is the complet page not available or only the wp-login page of your page?

Some guys like to password protect the Admin Area serverside. so that you have to enter a password before you can access the normal WP access.
Here is some info about htpasswd ( same as htaccess it is an invisible file with a dot in front: .htaccess and .htpasswd )
http://www.htaccesstools.com/articles/htpasswd/
The Protection then is an entry in htacces file like:

# Auth protect wp-login.php
<Files wp-login.php>
  AuthName "Restricted Admin-Area"
  AuthType Basic
  AuthUserFile /is/htdocs/wp1234567_EJ5MMWZBH6/www/.htpasswd
  Require valid-user
</Files>

# Deny access to important files
<FilesMatch "(\.htaccess|\.htpasswd)">
  Order deny,allow
  Deny from all
</FilesMatch>

you have to know the absolute path to the htpasswd to set this.
That’s a good thing, but annoying when logging into the WordPress backend.
But the advantage is that the attempts to hack into your admin area using a bot are already blocked on the server side, so that the brute force attack does not affect your site performance.

Ok – the one thing that is neccessary for wordpress itself is something like this :

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
…  things WP need for example to set up permalink structure etc …
</IfModule>
# END WordPress

Everything else can be useful but is not necessary.

i use the htaccess file often to set up gzip or expiration date etc. for WordPress files.
or to redirect old page path to new ones (301 redirect instructions)
