What is the Purpose of the Magento 2 OTP Login Extension?

“The mobile OTP login Magento 2 extension adds phone verification to e-commerce stores. It sends one-time passwords to registered mobile numbers for secure authentication.”

Store owners can enable OTP verification during registration, login, and checkout. The system prevents identity theft through single-use passwords and stops fake account creation. Customers can use either email or mobile numbers for verification. The extension works with multiple SMS gateways, such as Firebase and MSG91.

Store administrators can set custom OTP expiry times and message templates. Mobile verification reduces password-related security risks.

The extension supports both traditional password login and OTP authentication methods. Integration with existing Magento 2 stores requires minimal configuration.

Troubleshooting Feature-Centric Magento 2 OTP Issues

1. SMS Gateway Connection Problems

• The SMS gateway returns error 401 due to invalid API keys. You must verify the credentials in your configuration file at app/code/config/sms.xml.

• High traffic loads cause gateway timeouts during peak hours. Setting connection_timeout=30 in your gateway settings resolves timeout issues.

• Messages remain stuck in the pending queue without delivery. Running the command bin/Magento queue:consumers:start clears blocked message queues.

• SMS providers block rapid message sending as spam protection. Implementing gradual retry delays prevents rate limit blocks.

2. Mobile Number Validation Issues

• The system rejects valid international phone numbers. Installing libphonenumber-js library enables proper international number handling.

• Your database accepts duplicate phone numbers for different accounts. Adding a unique constraint to customer_mobile_number prevents duplicates.

• Phone numbers are saved without proper country codes. Setting default_country_code in store settings fixes missing codes.

• Customer checkout fails due to cached invalid numbers. A cache refresh after number updates resolves validation errors.

3. OTP Generation and Delivery

• OTP codes expire at the wrong times in different locations. Converting all time calculations to UTC fixes timezone issues.

• Simple random functions create predictable OTP patterns. Cryptographic random generators produce more secure codes.

• Old OTP codes remain active alongside new ones. Implementing automatic invalidation of previous codes prevents confusion.

• The system cannot confirm if SMS messages reached customers. Adding delivery status webhooks provides delivery confirmation.

4. Session Management

• OTP verification fails when sessions expire too quickly. Extended session timeouts allow complete verification.

• Users cannot log in from multiple devices simultaneously. Device-specific tokens enable multi-device support.

• Cached data prevents new OTP code validation. Regular customer_entity cache clearing enables new code verification.

• The system loses OTP data between page loads. Storing verification data in permanent storage maintains consistency.

5. Extension Compatibility

• The extension breaks with newer Magento versions. Updating composer.json version requirements prevents conflicts.

• Other modules interfere with OTP functionality. Setting higher module sequence priority maintains OTP operations.

• OTP pages display incorrectly with custom themes. Placing templates in the correct theme folders fixes display issues.

• API calls fail with 404 errors. Adding proper route definitions in routes.xml enables API endpoints.

Admin Options for Customer Action: OTP Validation Application

1. Registration Settings

• Enable OTP validation for new account creation. The system sends verification codes to mobile numbers during signup.

• Set custom OTP message templates for registration. You can personalize SMS content for different customer groups.

• Choose between numeric or alphanumeric OTP formats. Number-only codes work better for mobile input.

• Control OTP expiry time between 60 and 300 seconds. Shorter times increase security but may frustrate users.

2. Authentication Methods

• Configure email fallback when SMS fails. Messages automatically switch to email delivery on SMS errors.

• Set up multiple SMS gateway options. Different providers improve delivery reliability.

• Enable two-factor authentication, combining password and OTP. Extra security layers protect customer accounts.

• Allow customers to request new OTP codes. A 30 to 60-second delay prevents abuse.

3. Payment Validation

• Select specific payment methods requiring OTP verification. High-value transactions receive extra protection.

• Enable checkout OTP validation separately. Customers verify their identity before completing purchases.

• Set different OTP rules for guest checkout. Guest purchases may need stricter verification.

• Configure payment-specific message templates. Each payment method can have custom OTP text.

4. Mobile Number Management

• Set country code restrictions for phone numbers. Proper formatting prevents delivery failures.

• Enable mobile number updates with verification. Changes require new OTP confirmation.

• Prevent duplicate mobile number registrations. Each phone number links to one account.

• Add dial code caching for faster validation. API response caching improves performance.

5. SMS Gateway Configuration

• Enter SMS gateway API credentials. Valid authentication details enable message delivery.

• Choose between promotional or transactional SMS types. Message classification affects delivery priority.

• Configure sender ID for brand recognition. Customers see your store name in messages.

• Test SMS delivery before going live. Verification prevents production issues.
