In today’s mobile-driven world, delivering smooth and secure login experiences is critical to eCommerce success. With over 7.4 billion smartphone users globally, allowing customers to sign in using their mobile numbers is no longer just a convenience—it's a strategic necessity. For Magento 2 merchants, enabling mobile login can streamline access, reduce abandonment rates, and fortify user authentication.
Why Mobile Number Login Is Gaining Popularity
Compared to traditional email-based logins, using mobile numbers offers several significant benefits:
- Greater Convenience: Users typically carry their phones everywhere and are more likely to remember their mobile number than email credentials.
- Improved Security: OTP-based verification introduces an extra layer of protection against unauthorized account access.
- Faster Checkout: By simplifying the login process, mobile authentication helps reduce friction and checkout abandonment.
- Cross-Device Consistency: Mobile numbers stay consistent across devices, making multi-device sign-ins hassle-free.
This article explores how Magento 2 store owners can successfully implement mobile number login, covering key considerations, best practices, and reliable extension options.
How Mobile-Based Authentication Works in Magento 2
The typical mobile login workflow includes:
- User Entry: Customers provide their mobile number on the login or registration page.
- OTP Generation: A one-time password is sent to the provided number via SMS.
- Code Verification: The user inputs the received code.
- Account Access: If the code is valid, the user is logged in.
This method can either replace or complement the traditional email/password login process, offering a smoother and more secure user experience.
Magento 2’s Built-in Capabilities and Gaps
Magento 2 doesn’t offer native mobile number login functionality. Adding this feature from scratch involves complex customization and integration with SMS gateways. Challenges include:
- Development overhead for secure OTP generation and validation
- Ensuring regulatory compliance for SMS communications
- Maintenance during core updates and version upgrades
Due to these limitations, many store owners opt for third-party extensions tailored to offer seamless mobile authentication.

Use fallback options (e.g., email verification), enable retries, and work with multiple SMS gateways.
2. Formatting Errors for International Numbers
Use libraries for phone validation and formatting, and add clear guidance and examples.
3. User Reluctance to Share Numbers
Educate users about the benefits and your privacy policy. Allow optional adoption initially.
