## Description

SnWebTech SMS OTP Authentication lets users register and log in to a WordPress site
using a One-Time Password (OTP) sent to their mobile number.

The plugin integrates with the **SnWebTech SMS Gateway Pro Bulk SMS** external SMS
service at https://snbulksms.in. An active account and API credentials from the 
service are required to send OTP messages.

The plugin does not include a license activation system or paywall. The WordPress.
org version provides its included functionality without requiring a license key.

### External Services

This plugin connects to **SnWebTech SMS Gateway Pro Bulk SMS**, an external SMS 
service operated by SnWebTech.

Service website: https://snbulksms.in

The service is required for sending OTP messages. When a visitor requests an OTP,
the plugin sends the recipient’s mobile number, OTP message content, sender information,
DLT template information, and the configured API credentials to the service’s API
endpoint. The plugin also connects to the service when an administrator uses the
gateway balance check or test SMS tools.

The plugin uses these service endpoints:
 * `https://snbulksms.in/api/send.php` —
sends OTP/test SMS messages. * `https://snbulksms.in/api/balance.php` — checks the
account balance when requested by an administrator.

Please review the service provider’s own terms and privacy information before using
the service.
