Guide for Magento 2 Firebase OTP Login Extension

Updated 6 March 2024

Magento 2 Firebase OTP Login extension allows the users to register seamlessly using the OTP sent to the user’s mobile device or email address.

Apart from that, an OTP/email OTP is sent at the time of the forget password verification procedure for changing the password.

The login verification also requires verification via the OTP sent to the user’s mobile device and email address.

Implementing Magento 2 OTP login via mobile number and email in a Magento 2-based e-commerce store can enhance security, improve user experience, and provide several business benefits.


  • Admin can enable/disable the OTP module from admin configuration.
  • Mobile/Email OTP verification at customer registration.
  • Mobile/Email OTP verification at customer login.
  • Mobile/Email OTP verification at the forgot password page.
  • Mobile/Email OTP verification when users have to log in during checkout.
  • Admin can select Email templates from the system to be used for OTP verification notifications.
  • The extension is compatible with the Hyva Theme.
