A lot of web sites, even well known ones (newspapers, telcos, …) adopts 
WordPress as their CMS. WordPress is a great platform, however it 
can happen that password leaking or guessing might lead to unauthorized 
access to the platform. A potential attacker can be therefore able to 
change articles, part of the web site and/or make the website unavailable, 
with image and economic damages for a company or for a blogger. 
This is even more true if your website is not SSL protected.
SecurePass is a SaaS service offering an easy and affordable solution 
for One Time Passwords (OTP) and strong authentication in general. They 
offer 5 users for free included with their standard (=basic) account, which 
is more than enough for standard blogs and web sites. Companies can purchase 
additional users, if needed.
More information on the section “Setup and configure SecurePass” in Other Notes.

<h3>Setup and configure SecurePass</h3>
If you don’t own already an account with SecurePass, you can sign-up for a new account here: http://www.secure-pass.net/open
Note: Use “misec2011” as promo code, it will give you an entitlement for using 
SecurePass up to 10 users for 2 years free-of-charge. Without any promo code, 
you will have 5 users for 20 years for free. It depends on what you need (more users or more years).
Connect to the admin interface on https://admin.secure-pass.net 
and create a new device (basically a RADIUS client).
In the admin interface, go to the “Device” section and add a new device. 
You will need to set the public IP Address of the server, a fully qualified 
domain name (FQDN), and the secret password for the radius authentication. 
It’s ok if your web server is behind a firewall and/or NAT, ensure that 
your server has rights to send (and receive) RADIUS authentication requests, 
i.e. UDP port 1812.
