Introduction
User registration and login have always been among the main concerns of WordPress site administrators. The Digits plugin solves this problem by enabling mobile number registration and quick login.
However, since this plugin relies on SMS, many users face limitations and high costs. The best solution is to connect Digits to WhatsApp.
With this method, instead of receiving an SMS, users will receive their verification code (OTP) directly in WhatsApp—faster, cheaper, and without restrictions.
What is Digits and why is it popular?
The Digits plugin is one of the most widely used WordPress plugins for user registration and login. This plugin:
- Enables quick registration with a mobile number
- Supports passwordless login
- Provides two-factor authentication (2FA)
- Is fully compatible with WooCommerce and WordPress
🔹 The main issue is its dependency on SMS, which is often unreliable or costly. Replacing SMS with WhatsApp completely solves this limitation.
