Descriere
Login with WhatsApp (Reverse OTP) allows users to authenticate by sending a message via WhatsApp to the admin number instead of receiving a code. This unique method, called Reverse OTP, ensures that the user is the initiator of the conversation, drastically reducing the chances of the admin number being blocked by WhatsApp.
This plugin is ideal for login, membership, or community-based WordPress websites where mobile-based verification is preferred over email/password.
Third-party Service
This plugin requires a third-party service to function properly. It integrates with the external Whatsiplus API in order to provide OTP-based login functionality via WhatsApp.
The plugin communicates with the following endpoints from the service:
- API Base URL: https://api.whatsiplus.com
- Send Message: https://api.whatsiplus.com/sendMsg
- Receive Message: https://api.whatsiplus.com/receivedMessages
- Service Settings: https://api.whatsiplus.com/serviceSettings
What data is sent and when:
- During login or OTP request: The plugin sends the user’s phone number (as entered by the user) and your API key to the Whatsiplus service in order to initiate OTP verification.
- During plugin configuration: The plugin sends your API key to verify service status and fetch related settings (such as connected number and country code).
No other personal data is transmitted to Whatsiplus.
Requirements:
This plugin will not work without a valid Whatsiplus API key. You can obtain a key by registering at https://whatsiplus.com.

Întrebări frecvente

Why is this called Reverse OTP?
-
Because instead of sending the OTP to the user, the user sends the OTP to you — on WhatsApp. This prevents spam detection and your number won’t get blocked.
-
Is this plugin safe and secure?
-
Yes. Only a valid OTP sent to your registered WhatsApp number from a matching user phone number is accepted.
-
Does it require WooCommerce?
-
No. WooCommerce is optional. The plugin can detect phone numbers from standard or custom user meta fields.
-
Can I use it for mobile apps?
-
Yes! REST API support is included so you can integrate it into mobile apps or external platforms.
-
Can I customize the welcome message?
-
Yes, you can change the welcome message from the plugin settings.
