In the user registration process, every additional input field can cause potential customers to drop off. Password entry, email verification, repeated confirmation—these traditional steps are quietly dragging down your site's growth. The Digits plugin uses phone number OTP verification to completely eliminate the password field, allowing users to simply enter their phone number and receive a verification code to log in. According to official data, this change can lead to a 76% increase in new users. This article provides a complete Digits tutorial and professional review, covering installation, configuration, advantages, use cases, and frequently asked questions.
1. What is Digits? Core Features Overview
Digits is a WordPress plugin designed specifically for phone number registration and login, developed by the UnitedOver team and available on CodeCanyon. Its core concept is "passwordless" authentication—users verify their identity by receiving a one-time password (OTP) via SMS, eliminating the need to remember passwords or verify emails. This model is especially popular on mobile, as phone numbers serve as a "digital ID" that users always carry.
Beyond basic features, Digits also supports social login (Google, Facebook, etc.), Passkey login, WooCommerce integration, multisite compatibility, and community plugins like BuddyPress. Its built-in drag-and-drop form builder lets you freely design the layout and fields of your registration page.
2. Core Advantages of Digits: Why Choose It?
Compared to traditional email+password registration, Digits shows clear advantages across multiple dimensions. Below, we break it down from three angles: conversion rate, security, and compatibility.
2.1 Conversion Rate Boost: Remove Passwords, Skyrocket Registrations
What do users hate most? Setting complex passwords, confirming emails, and recovering passwords. Digits cuts these steps out entirely. Users just enter their phone number, click to get a verification code, and complete registration in under 30 seconds. According to official case studies, one e-commerce site saw a 76% increase in new user registrations after implementing it.
2.2 Enhanced Security: OTP Dynamic Verification Prevents Credential Stuffing
Password leaks are the top threat to website security. OTP codes are time-sensitive (typically 60-300 seconds) and regenerated for each login, so even if a database is breached, attackers cannot use static passwords for credential stuffing attacks. Digits also supports limiting the frequency of verification code sends for the same phone number to prevent SMS bombing.
2.3 Compatibility and Flexibility: Adapts to Major Ecosystems
Digits deeply integrates with major plugins like WooCommerce, BuddyPress, Ultimate Member, and LearnDash. Whether you're building an e-commerce site, community forum, or online course platform, Digits can seamlessly replace the existing login system. It also supports multisite networks, making it suitable for enterprise-level deployments.

3. Use Cases: Which Websites Benefit Most from Digits?
Digits isn't a one-size-fits-all solution, but in the following scenarios, its value is maximized.
- E-commerce Sites (WooCommerce): Mobile shopping is now mainstream, and phone number registration can significantly reduce cart abandonment rates. Users don't need to register before ordering; they can verify via phone number at checkout for a smooth experience.
- Membership Communities (BuddyPress/Ultimate Member): Community platforms need rapid user influx, and lowering the registration barrier is key for cold starts. Digits' social login feature can further drive user acquisition.
- Online Course Platforms (LearnDash/Tutor LMS): Students may come from different countries, and email verification can sometimes be blocked, making phone number OTP a more direct and reliable option.
- Enterprise Internal Portals: Using corporate phone number ranges for login, combined with OTP verification, is both secure and easy to manage.

5. Frequently Asked Questions (FAQ)
Which SMS gateways does Digits support?
Digits includes built-in support for over 20 SMS gateways, including Twilio, AWS SNS, Nexmo, Plivo, ClickSend, and TextLocal. You can select the gateway type directly in the plugin settings and enter the corresponding API Key and Secret. If you use SMS services in China, you can also integrate via a custom API interface.
Is Digits compatible with WooCommerce?
Fully compatible. Digits can replace WooCommerce's default login and registration forms and supports phone number verification directly on the checkout page. Users don't need to create an account to place an order; they just enter their phone number and receive a verification code to confirm their identity. Additionally, Digits supports WooCommerce subscriptions, memberships, and more.
How do I set the OTP validity period in Digits?
In the Digits backend under "OTP Settings," you'll find the "OTP Validity Period" option, which defaults to 5 minutes. You can adjust it to any value between 1 and 30 minutes based on your business needs. We recommend keeping it at 3-5 minutes to balance security with giving users enough time to enter the code.
Does Digits support Multisite?
Yes. Digits is fully compatible with WordPress multisite networks. You can apply global settings on the main site or allow subsites to independently configure their own SMS gateways and form styles. This is particularly useful for enterprises operating multiple brands or regional sites.
What is Digits' pricing model?
Digits uses a one-time purchase model, with a standard price of $49 on CodeCanyon. This includes 6 months of free support and updates. After that, you can choose to renew to continue receiving support and updates, typically at around 50% of the original price. Compared to monthly subscription SaaS products, a one-time purchase offers better value.
6. Purchase Advice: Who Should Get Digits?
If you run a website targeting mobile users, or if your user base is resistant to email verification (e.g., in some developing countries where phone numbers are more common than emails), Digits is a highly worthwhile investment. Its passwordless design not only improves user experience but can directly translate into higher registration conversion rates.
However, if your site's user base is primarily on desktop and accustomed to email login, introducing phone number registration might cause confusion. Additionally, if your site has very low traffic (fewer than 10 daily registrations), the improvement from Digits may not be as noticeable—though planning for mobile experience early is always a wise long-term move.
