This class can authenticate users once using codes sent via SMS.
It can take a phone number of a user to authenticate and sends a HTTP request to a local server script that will send a SMS message to that number with a generated password using the TxtLocal API.
The generated password is stored in a MySQL database for subsequent verification.
The class can also verify the password entered by the user to authenticate him as owner of the given phone number by sending another HTTP request to the local server script to check the database to verify if the password is correct.

|One way to verify and authenticate a person is to send a SMS message to phone that he owns.
When combined with password based authentication, this forms what is called two factor authentication. It verifies one thing that the person knows, the password, and verifies one thing that he owns, the phone.
This class can help performing two factor authentication by sending a SMS message with a secret code that the user needs to enter in a Web page to prove that he owns the phone with the number that he supplied.
