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.

Chap Secure Password Login

Do not show password, during login, on an insecure channel (without SSL). Use a SHA-256 hash algorithm.

WordPress 4.5 added the ability to login using the registered user’s email address in place of the username. When this plugin is active, the ability to login using the email address in place of the username is removed, and the label of the input field is changed to reflect this.

No Login by Email Address

Removes the ability to login using the email address instead of the username.
