## Description

OneCode Login provides a modern, passwordless authentication experience for your
WordPress site. Instead of traditional passwords, users receive a secure 6-digit
verification code via email.

#### Key Features

 * **Passwordless Authentication** – Users log in with just their email address
 * **6-Digit Verification Codes** – Secure, time-limited codes sent via email
 * **Rate Limiting** – Built-in protection against brute force attacks
 * **Request ID Binding** – Each code is bound to a specific login session for enhanced
   security
 * **Neutral Feedback** – Prevents user enumeration attacks by not revealing if 
   an email exists
 * **Customizable** – Configure expiry times, cooldowns, and email templates
 * **Accessible** – Full keyboard navigation and screen reader support
 * **Gutenberg Block** – Easy to add login forms to any page
 * **Shortcode Support** – Use [onecode_login] anywhere
 * **wp-login.php Integration** – Optionally replace the default WordPress login

#### Security Features

 * Cryptographically secure code generation
 * Configurable code expiry (default: 10 minutes)
 * Resend cooldown to prevent spam
 * IP-based and email-based rate limiting
 * Automatic lockout after failed attempts
 * Codes are single-use and invalidated after successful login

#### Use Cases

 * Membership sites where password fatigue is an issue
 * Customer portals requiring simple authentication
 * Internal tools where security without complexity is needed
 * Any site wanting to improve user experience

## Installation

 1. Upload the `onecode-login` folder to `/wp-content/plugins/`
 2. Activate the plugin through the Plugins menu in WordPress
 3. Go to Settings > OneCode Login to configure options
 4. Add the login form using the [onecode_login] shortcode or Gutenberg block

#### Shortcode Options

 * `redirect_to` – URL to redirect after successful login
 * `button_text` – Custom text for the send code button
 * `verify_text` – Custom text for the verify button

Example: `[onecode_login redirect_to="/dashboard" button_text="Get Code"]`

## FAQ

### Does this replace password login completely?

By default, no. OneCode Login works alongside traditional password login. However,
you can enable the “Replace wp-login.php” option to use OneCode Login as the primary
login method.

### What happens if the email does not arrive?

Users can request a new code after the cooldown period (default: 60 seconds). Check
your server email configuration if emails consistently fail to deliver.

### Is this secure?

Yes. The plugin uses cryptographically secure random number generation, time-limited
codes, rate limiting, and request binding to prevent various attack vectors.

### Can I customize the email template?

Yes. Go to Settings > OneCode Login > Email tab to customize the subject and body
of verification emails. You can use placeholders like {code}, {expires}, {site_name},
and {user_email}.

### Does it work with multisite?

The plugin is designed for single-site installations. Multisite compatibility may
be added in future versions.

### What if a user does not have an account?

The plugin only allows existing users to log in. For security reasons, it does not
reveal whether an email address has an account – users always see the same “check
your email” message.
