PLEASE CHECK YOUR EMAIL SETTINGS IN YOUR PROFILE BEFORE LOGOUT THE FIRST TIME AND WAIT FOR THE MAIL CONTAINING THE SECURE CARD. THANK YOU –

A new field is added below the password one.
</li>
<li>It requires a new code, this code is on a “MSL Secure Card” (png or html table).</li>
<li>This card contains 64 codes, each code contains 4 chars. You have to print it!</li>
<li>Now when someone wants to log on any account, even if he knows the password, he can not use it without the code.</li>

This kind of authentication is called “Strong Authentication”, strong authentication is associated with at least two-factor authentication. 
Your usual password is the first and only factor, this plugin adds an external factor : a MSL Secure Card. 
Now, you have 2 secure factors to log in.
When someone wants to log in any account, he has to fill the username, password and now a “MSL Code” field. 
This code is printed on a card (you have to print it) and contains a code from A1 to H8. 
Without this code, he can not log in!
The codes are not stored in your DB, all codes are hashed like your password is. So, the codes are as secure as your password is.
Every blog which needs to improve its login’s security needs this plugin.

This is a strong authentication plugin. You have to fill a second field, kind of password but this one comes from a printed card you own (FR/EN).

For some reason or other, you might want to allow access to certain posts only to certain people. You can use password-protection on Pages and Posts, but those need to be set individually. 
It’s far simpler to just write a Post, specify a category and all posts in that category are password protected. Or you might decide to protect a lot of old posts. 
Imagine a family blog where certain posts are only visible to people who know the birthday of your first child, or remember your pet’s name. 
Cat-Pass is not for super-sensitive information, it’s for casual use.

Cat-Pass

Cat-Pass lets you password-protect categories. Caution: deactivating the plugin will render your protected posts visible again.
