FireMobile WordPress & WooCommerce Firebase Mobile OTP authentication

FireMobile - Mobile OTP Authentication via Firebase for WordPress and WooCommerce

FireMobile is a plugin that integrates Firebase's phone authentication mechanism with WordPress and WooCommerce stores. The solution uses SMS one-time-transfer codes (OTPs) for registration, login, and phone number verification during order placement. FireMobile makes the authentication process faster, less susceptible to forgotten passwords, and better suited for mobile users.

FireMobile functionalities

• Phone verification powered by Firebase Phone Authentication (SMS OTP) - passwordless login and registration.
• WooCommerce integration – number verification at checkout, forced phone confirmation for new accounts and orders.
• Responsive phone number form with automatic country code recognition and format validation.
• Short login option: just your phone number and OTP code, no need to remember a password.
• Passing the verified number to the WordPress/WooCommerce user profile and mapping to account metadata.
• Code resending mechanisms, attempt limit, and configurable OTP validity period.
• Shortcodes and widgets to embed login/registration forms anywhere on the page.
• Extensible actions and filters for developers - ability to customize logic after OTP verification.
• Language versions and translation options (gettext), compatibility with popular multilingual plugins.

Benefits for shops and services

• Increase conversion rate: Simple SMS login reduces barriers to registration and order completion.
• Better mobile experience: Users no longer need to type long passwords on mobile devices.
• Reduce fraud and fake accounts: Phone number verification makes it harder to create mass bot accounts.
• Simplify the access recovery process – an alternative to traditional password reset procedures.
• Ability to personalize communication – a verified number is a valuable contact channel for notifications and reminders.

Applications and use cases

• WooCommerce online stores requiring quick customer verification at checkout or when registering an account.
• Social networking sites and advertising platforms that want to reduce the number of fake profiles.
• Service portals offering reservations or orders with immediate confirmation via SMS.
• E‑commerce applications focused on mobile users, where convenience and speed of authorization are key.

Integration, configuration and requirements

FireMobile requires a configured Firebase project with Phone Authentication enabled and the project's API keys. After entering the configuration data in the WordPress dashboard, the administrator can configure the plugin's behavior: which forms use OTP, whether verification is mandatory at checkout, and rules for code sending limits. The plugin works with the WordPress accounts system and maps verified numbers to user profile fields, making it easier to manage customer data later.

Additionally, FireMobile offers options for customizing screens and messages, the ability to enable additional server-side validation, and extensible hooks for integration with other store plugins and modules.

FireMobile is designed for website and store owners who want to implement a modern, passwordless authentication mechanism powered by Firebase. This solution makes the registration, login, and phone verification process simpler, faster, and more mobile-friendly, resulting in higher conversions and greater customer trust.
