Whenever you try to login into your website, you can use this plugin to trasmit your password encrypted. The encryption process is done by the Chap protocol; this is particularly useful when you can’t use ssl or other kinds of secure protocols. By activating the ChapSecureLogin plugin, the only information transmitted unencrypted is the username; password is hided with a random number (nonce) generated by the session – and opportunely transformed by the SHA-256 algorithm. 
In the first login there will be an error, but don’t worry is only a tecnical error. Indeed in the next login’s operation, if the values are correct, there will not be errors, but you give mind because the password will sended in unencrypted way.

This is a zero-configuration plugin.
