One-time Password by Email for WooCommerce

Do you cringe every time you remember your store’s password reset link? You’re not alone. A recent analysis found that more than 18 percent of Amazon users abandoned their carts because they forgot their password or encountered a clunky reset process. Password friction doesn’t just frustrate shoppers – it costs businesses revenue. In a world where people expect instant gratification, removing needless hurdles in the login process is key to better conversion. That is why passwordless, one‑time‑password (OTP) authentication is gaining traction: it reduces cognitive load and friction, letting customers focus on shopping rather than resetting credentials.

Why passwordless login matters

Traditional password flows ask users to create a secure password, remember it and then type it correctly on future visits. If they forget, they must navigate a reset flow, find the reset email and create yet another password. As the Baymard Institute’s study (highlighted above) shows, this friction causes abandonment. Passwordless authentication removes those obstacles: users simply prove ownership of an email address or phone number and then get access. Industry researchers note that reducing login friction directly improves conversion rates and keeps users focused on their goal.

Meet MRKV OTP by Email

MRKV OTP by Email is a lightweight plugin that brings passwordless magic to WooCommerce. Instead of forcing shoppers to remember a password, it offers a pop‑up form where they can enter their email address. A secure six‑digit code is sent to their inbox; they enter that code into the form and are immediately logged in. If the email doesn’t belong to an existing user, the plugin quietly creates an account for them. No passwords to remember. No reset links. Just frictionless access.

How it works

Two‑step modal – The plugin registers a shortcode [otp_login_popup], which renders a discreet “Login / Register” button anywhere in your theme. When clicked, a beautifully styled modal appears with an email input field and a “Get Code” button. Once the user submits their email, the plugin hides the first step and presents six small OTP boxes for entering the code. The boxes auto‑advance as the user types; pasting the entire six‑digit code is also supported.

Instant code delivery – The plugin generates a random six‑digit OTP and stores it in WordPress transients for ten minutes. It then uses WooCommerce’s email templates to send the code to the user. The subject line and message are customizable, and because it piggy‑backs on WooCommerce’s mailer, your branding and reply‑to address remain consistent.

Secure AJAX endpoints – The code uses WordPress nonces to protect both the “send OTP” and “verify OTP” actions. Email addresses and OTP values are sanitized server‑side, and incorrect codes trigger an error message without logging the user in. After a successful verification the OTP transient is deleted, the user is authenticated via WooCommerce’s standard wp_set_auth_cookie and the page reloads so they see their account information.

Automatic account creation – If a customer’s email isn’t associated with an existing user, the plugin creates a new WooCommerce customer record behind the scenes. Shoppers never leave the modal; they simply enter the code and they’re in.

Multi‑language ready – The plugin detects your site’s current WPML/Polylang language and switches its labels between English and Ukrainian automatically. Strings like “Login by Email”, “Get Code” and “Login” are stored in an array, so you can easily add translations for other languages.

Why merchants love it

Better conversions and lower abandonment – By removing password fields and reset links, you dramatically reduce drop‑offs at the login step. Research shows that shoppers are more likely to convert when authentication is convenient. MRKV OTP by Email offers that convenience while still verifying identity.

Reduced support burden – Forgotten passwords are a major source of support tickets. Allowing customers to log in with an OTP eliminates password reset requests, freeing your team to focus on value‑added tasks. Similar passwordless implementations have been shown to reduce auth‑related support tickets by up to 50 percent.

Enhanced security – Passwordless doesn’t mean less secure. Each OTP is randomly generated, valid for only ten minutes and tied to a single email address. The plugin uses WordPress nonces and sanitization functions to prevent misuse. Because the code is delivered via your WooCommerce mailer, there are no third‑party dependencies.

Fits your brand – All labels and styles can be customized to match your site’s look and feel. The modal uses your existing fonts, and you can override colours with simple CSS. The email template uses WooCommerce’s default header and footer, ensuring consistent branding across transactional messages.

Easy to implement – Installation is as simple as uploading the plugin and adding the [otp_login_popup] shortcode to the page where you want the login button. There is no need to override templates or write custom code. Developers appreciate that the plugin is self‑contained, uses WordPress actions and filters and doesn’t bloat your site.

A smarter login for your store

Localization experts remind us that small improvements – like clear language choices and frictionless interactions – have a big impact. When digital experiences feel native and intuitive, users spend more time on the site, bounce less and trust your brand more. MRKV OTP by Email is one of those small yet powerful enhancements: it removes the roadblocks of traditional login and invites shoppers back with a simple email code. The result? Happier customers and healthier conversion rates.
