Mobile OTP Login & Registration

Key Features

OTP verification at four flows: registration, login, forgot-password, and checkout account creation

SMS-first OTP with automatic email OTP fallback when delivery fails or no mobile is on file

Gateway adapter layer supporting MSG91, Twilio, Unifonic, Africa's Talking, Firebase, and 50+ SMS providers

Phone-first, email-optional signup — phone number becomes the primary login credential

Admin-configurable OTP length, expiry window, resend cool-down, and maximum attempt limits

Built as a native module under app/code with di.xml plugins, observers, and a reusable OtpServiceInterface service contract

GraphQL and REST mutations/endpoints for headless / PWA storefronts to request and verify OTPs

Admin ACL-protected configuration (Ecosire_MobileOtpAuth::config) with per-store-view enable/disable

Rate limiting and brute-force protection with cron-based purge of expired OTP records

International phone number normalization with country-code handling and RTL/locale-aware UI

Audit logging of OTP requests, verifications, and failures for security review

Graceful degradation: if a gateway is down, fallback path keeps customers able to authenticate

About this Product

Email-and-password signup is friction in markets where customers think of identity as a phone number, not an inbox. This extension makes the phone number the primary credential: a customer enters their mobile, receives a one-time passcode (OTP) by SMS, types it back, and they're registered or logged in — no password to create, forget, or reset.

ECOSIRE builds this as a proper Magento 2 module under app/code/Ecosire/MobileOtpAuth, wired into the framework rather than bolted on. We use plugins/interceptors around Magento\Customer\Model\AccountManagement and the customer login controllers, an observer on customer_register_success, and a dedicated OtpServiceInterface service contract so the verification logic is reusable across web, GraphQL, and REST storefronts (handy for PWA / headless builds). OTP gating is applied at four points: registration, login, forgot-password, and checkout (guest-to-account at the payment step).

A gateway adapter layer lets us connect the SMS provider you already use or want — MSG91, Twilio, Unifonic, Africa's Talking, Firebase Phone Auth, and 50+ others — with email OTP as an automatic fallback when an SMS send fails or the destination is undeliverable. Everything sensitive lives in the admin behind proper ACL (Ecosire_MobileOtpAuth::config): OTP length, expiry window, resend cool-down, max attempts, and per-store-view enablement via system.xml/config.xml. A cron job purges expired OTP records and throttles brute-force attempts.

Because it's build-to-order, we tailve it to your Magento version (Open Source or Adobe Commerce), your theme's checkout, your locale/RTL needs, and your chosen gateway — then install it on your environment and support it. This is not an instant Adobe Commerce Marketplace download; it's a clean, store-specific build delivered and maintained by our engineers.

Who this is for

Regional retailer in a phone-first market

Sells in the GCC, South Asia, or Africa where shoppers identify by mobile number, not email. Wants frictionless password-less signup to lift account creation and repeat purchases.

Conversion-focused store owner

Sees cart abandonment at the account-creation step and wants to remove the password barrier while keeping checkout secure with verified phone identity.

Magento developer / agency lead

Needs a clean, upgrade-safe module that uses proper plugins, service contracts, and GraphQL — not a hack that breaks on the next Magento patch — and prefers to hand the build to a specialist.

Frequently Asked Questions about Mobile OTP Login & Registration

Is this an instant download from the Adobe Commerce Marketplace?

No. This is a build-to-order extension. ECOSIRE builds the module specifically for your Magento version, theme, and chosen SMS gateway, then installs and supports it on your environment. There is no instant marketplace download or self-serve license key — you get a tailored, installed solution.

How long does delivery take?

A standard build is typically delivered within about 5 to 10 business days after we confirm your Magento version (Open Source or Adobe Commerce), your preferred SMS gateway and its credentials, and which flows you want OTP-gated. Heavier customizations (unusual checkout themes, multi-store/RTL, headless GraphQL integration) can extend that, and we give you a firm timeline before starting.

What ongoing support and updates do I get?

Every build includes a warranty period for bug fixes after delivery. Beyond that, we offer an optional support and maintenance arrangement that covers compatibility with Magento security patches and version upgrades, gateway changes, and small enhancements. Because we keep the module source clean and standards-based, upgrades stay straightforward.

Which SMS gateways can you connect?

We build a gateway adapter so we can connect MSG91, Twilio, Unifonic, Africa's Talking, Firebase Phone Auth, and 50+ other providers. If you already have an SMS account, we use it; if not, we advise on a good fit for your region and volume. Email OTP is wired in as an automatic fallback when an SMS send fails.

Will it work with my headless / PWA storefront?

Yes. We expose OTP request and verification through GraphQL mutations and REST endpoints backed by a service contract (OtpServiceInterface), so a PWA Studio or custom headless front end can drive the same verified-phone authentication as the Luma/classic storefront.

Does removing passwords make my store less secure?

No. A verified OTP proves possession of the phone number at each sensitive action, and we add rate limiting, configurable attempt caps, short OTP expiry, brute-force throttling, and audit logging. For high-risk flows you can keep OTP at checkout in addition to login, so account takeover is harder than with a static reused password.
