Authyo Passwordless Login enables secure OTP login for WordPress using email-based one-time passwords. It replaces traditional passwords with a modern passwordless authentication system that improves login security and simplifies the user experience.

Users simply enter their email address, receive a one-time password (OTP), verify the code, and are automatically logged in — no passwords required.

This plugin is officially developed and maintained by Konceptwise Digital Media Pvt. Ltd. and uses Authyo’s secure OTP authentication infrastructure.

With Authyo Passwordless Login, WordPress administrators can implement passwordless login, improve account security, and eliminate risks related to password leaks or weak credentials.

• No passwords stored or required
• Secure token-based authentication (single-use and time-limited)
• OTP delivered via Authyo’s secure email service
• Fallback Method: Optional two-factor authenticator app if email OTP fails
• Works with the default WordPress login page
• AJAX-powered login flow (no page reloads)
• Automatic dashboard redirect after successful login

How It Works

How to Use Authyo Passwordless Login

External Services

This plugin connects to Authyo’s external API to send and verify one-time passwords (OTP) for passwordless login functionality.

What data is sent:
– User email address (sent to Authyo API when requesting OTP)
– OTP code (sent to Authyo API for verification)
– Mask ID (returned by Authyo API, used for OTP verification)

When data is sent:
– When the user requests an OTP: Email address is sent to Authyo API
– When the user submits an OTP for verification: OTP code and Mask ID are sent to Authyo API

Authentication Flow:
– After successful OTP verification via Authyo API, the plugin generates a secure single-use token using WordPress core functions
– This token is browser-bound using a hashed User-Agent signature to prevent session hijacking
– The token is stored temporarily in WordPress transients and expires after 5 minutes
– The token allows WordPress to complete authentication without requiring a password
– Token is deleted immediately after verification (single-use security)

Purpose:
– To verify ownership of the provided email address through OTP verification
– After successful OTP verification, a secure browser-bound login token is generated
– The token allows WordPress to authenticate users without passwords

Data Storage:
– OTP session data (email, user ID, mask ID) is stored temporarily in WordPress transients (expires after 10 minutes)
– Login tokens are stored temporarily in WordPress transients (expires after 5 minutes and deleted immediately after use)
– No user data is permanently stored by this plugin
