Features

WordPress Login OTP
Add two-factor SMS verification to the default WordPress login form. After username and password are accepted, an OTP is sent to the user’s saved phone number. Supports Password + OTP mode. Users without a saved phone number are allowed to log in normally and are reminded to add a phone number from their profile page.

• Configurable OTP mode: Password + OTP, Phone + OTP, or Email/Username + OTP.
• “Remember verified device” option with configurable expiry (days).
• Restrict OTP enforcement to specific user roles (e.g. administrator, editor, shop_manager).
• Resend OTP button with AJAX support.
• Non-JS fallback form.

WordPress Registration OTP
Verify the phone number entered during WordPress default registration before the account is created.

• Customizable phone field label.
• Optional phone number requirement.
• Block duplicate phone numbers across accounts.

WooCommerce Order SMS Notifications
Send SMS notifications to both the store admin and customers when WooCommerce order events occur.

• Admin SMS on new order (configurable admin phone number).
• Customer SMS on: Processing, Completed, Cancelled, Failed, and Refunded order statuses.
• Each event can be toggled individually.
• Message templates use dynamic variables (order number, total, customer name, etc.).

Custom SMS Notification
Trigger one-off SMS messages from the admin Tools page or from your own code.

• Restrict the Tools sender to administrators only.
• Configurable default log context.

Developer API
Enable PHP helper functions, action hooks, and filter hooks for use in themes, plugins, and custom integrations.

Privacy & Data

SMSKora stores SMS log records (recipient, message status, provider, context) and OTP records (hashed OTP, phone, expiry) in custom database tables. No data is sent to third-party servers by this plugin. Data is sent only to the SMS gateway you configure. All stored data is deleted when the “Delete Data on Uninstall” setting is enabled.

External services

SMSKora connects to external SMS gateway APIs only when a site administrator configures an SMS provider and the plugin sends an SMS message, OTP message, order notification, login verification message, registration verification message, or balance-check request.

The plugin does not send SMS data to servers controlled by the SMSKora plugin author. SMS data is sent only to the SMS gateway provider selected and configured by the site administrator.

For configured providers, the following data may be sent to the selected provider:

• Recipient phone number.
• SMS message body.
• Sender ID or sender number, if configured.
• API key, access token, username, password, or other gateway credentials required by the provider.
• Request metadata required by WordPress and the remote API, such as the site server IP address and HTTP request headers.
• For balance-check requests, the plugin sends the configured API credentials to the selected provider to retrieve the account balance.

No external SMS gateway request is made unless the administrator configures a provider and a plugin feature triggers an SMS send or balance check.
