Protect a site with AuthPilot API, a two-step authentication that helps users to access a website using their phone number. This extra step is valuable because it adds security to blogs and websites with sensitive information. Users could be worry free of hackers’ attacks, since this authorization ensures the only person entering a site, is the user. AuthPilot features a RESTful official API and a PHP API. In the RESTful API, the site features the endpoints of create a user, update a user, text a user and call a user. Packagist and Github are two sources where developers can find additional documentation if they prefer to use the PHP API.
