WP_Application_Passwords WordPress Class
This class is used to generate and manage application passwords for WordPress. Application passwords are used to grant access to your WordPress site to third-party applications without needing to provide your username and password. This is useful for applications that need to access your WordPress site data, but that you don't want to grant full access to. To generate an application password, you first need to specify the application name and your WordPress username. Once you have done this, you can call the generate_password() method to generate a password for the application. This password can then be used by the application to access your WordPress site. If you need to revoke an application password, you can call the revoke_password() method. This will invalidate the password and prevent the application from accessing your WordPress site.
