Why OTP login is a big deal for a store<\/h2>\n\n- Fewer lost sales.<\/strong> No password reset emails standing between a customer and their order.<\/li>\n
- More customer accounts.<\/strong> Signing up takes seconds, so more guests become account holders you can bring back.<\/li>\n
- Every account has a verified mobile number.<\/strong> That is exactly what you need for SMS and WhatsApp order notifications<\/a>, COD confirmation, and abandoned cart messages.<\/li>\n
- Fewer fake and bot signups.<\/strong> A signup that needs a working mobile number keeps your customer list clean.<\/li>\n<\/ul>\n
Is it free?<\/h2>\n
Yes. The Fast2SMS plugin is completely free. There is no monthly fee. You only pay for the OTP messages you send, from your Fast2SMS wallet, at normal rates. A quiet day with no logins costs you nothing.<\/p>\n
What you need<\/h2>\n\n- A WordPress site with WooCommerce active.<\/li>\n
- A free Fast2SMS account<\/a> and its API key.<\/li>\n
- Customers with Indian mobile numbers. Fast2SMS works with Indian 10-digit numbers only.<\/li>\n<\/ul>\n
Step 1: Install the free plugin<\/h2>\n
Install it from the official WordPress plugin directory. In your WordPress admin go to Plugins > Add New<\/strong>, search for Fast2SMS<\/strong>, click Install Now, and activate it. You can also get it from the official plugin page<\/a>.<\/p>\nStep 2: Connect your Fast2SMS account<\/h2>\n
Copy your API key from the Dev API section of your Fast2SMS account and paste it into the plugin dashboard. The plugin shows your wallet balance when the key works. The full setup guide<\/a> walks through this step with screenshots.<\/p>\nStep 3: Turn on OTP login for My Account<\/h2>\n
Open the OTP & Login<\/strong> tab and switch on Login with OTP on the WooCommerce My Account page<\/strong>. If you also want new customers to verify their number when they register, switch on OTP verification on registration<\/strong> too.<\/p>\n\n ![\"OTP](\"https:\/\/www.fast2sms.com\/help\/wp-content\/uploads\/2026\/07\/fast2sms-otp-login-settings.png\")
Both switches live in the OTP & Login tab. You can send yourself a test OTP from here too.<\/figcaption><\/figure>\nWhat your customers see<\/h2>\n
On the My Account page, a Login with OTP<\/strong> box appears right below the normal login form. On the registration side, a Verify your mobile number<\/strong> box appears before the Register button.<\/p>\n\n ![\"WooCommerce](\"https:\/\/www.fast2sms.com\/help\/wp-content\/uploads\/2026\/07\/woocommerce-otp-login-my-account.png\")
Login with OTP on the left, mobile verification on signup on the right. Password login still works.<\/figcaption><\/figure>\nThe customer enters their 10-digit number and taps Send OTP. The box switches to the code step, with a resend timer so nobody can spam the button:<\/p>\n\n ![\"OTP](\"https:\/\/www.fast2sms.com\/help\/wp-content\/uploads\/2026\/07\/otp-verification-code-step-wordpress.png\")
Enter the OTP, tap Verify & Continue, and the customer lands back in My Account.<\/figcaption><\/figure>\nIf the number belongs to an existing customer, they are logged straight in. The plugin even matches the billing phone number from past orders. If the number is new, the plugin can create a customer account on the spot, with the verified number saved to the profile. You can turn that off if you prefer.<\/p>\n
A verified number helps across the whole order journey<\/h2>\n
OTP login is not just a nicer login. The verified mobile number it collects powers the rest of your store messaging:<\/p>\n
\n- Order updates.<\/strong> Send order placed, shipped, and delivered messages by SMS or WhatsApp<\/a>.<\/li>\n
- COD confirmation.<\/strong> Verify cash on delivery orders by OTP or a confirmation link before you ship, and cut fake orders.<\/li>\n
- Abandoned cart recovery.<\/strong> Remind customers about the cart they left behind.<\/li>\n<\/ul>\n
\n ![\"WooCommerce](\"https:\/\/www.fast2sms.com\/help\/wp-content\/uploads\/2026\/07\/woocommerce-checkout-cash-on-delivery-india.png\")
Checkout with cash on delivery. A verified number makes COD orders much safer.<\/figcaption><\/figure>\nBuilt-in safety<\/h2>\n\n- Store admin accounts are protected.<\/strong> By default an administrator account can never be opened with only an OTP, so a stolen SIM cannot take over your store.<\/li>\n
- Each OTP works once<\/strong> and expires quickly.<\/li>\n
- Resend cooldown<\/strong> keeps your SMS costs under control.<\/li>\n<\/ul>\n
Frequently asked questions<\/h2>\nIs WooCommerce OTP login free?<\/h3>\n

Do I need to change my theme?<\/h3>\n
