Password Protect >>>
This is undoubtedly the best password protection JavaScript you'll ever find. Besides supporting multiple users, multiple passwords, and even multiple destination pages (after they successfully login), this script is presented in a very easy-to-use interface that you're sure to love!
Add the below code to the <body> section of your page:
<center>
<table
border=1>

<select
