Step-by-Step: Plugin Implementation

Step 1: Choose and Purchase Plugin

1. Visit Magic Link Login for WordPress
2. Purchase license ($59)
3. Download ZIP file from your account

Step 2: Install Plugin

1. Log in to WordPress admin
2. Navigate to Plugins → Add New → Upload Plugin
3. Click Choose File and select downloaded ZIP
4. Click Install Now
5. Click Activate Plugin

Expected result: Plugin activated message appears

Step 3: Initial Configuration

1. Go to Settings → Magic Link Login for WordPress
2. Check Enable Magic Link Login for WordPress
3. Set token expiration time:
– Recommended: 15 minutes
– High-security sites: 10 minutes
– Slower email delivery: 20 minutes

4. Choose authentication mode:
– Magic Link Only – No password option (recommended for new sites)
– Hybrid Mode – Both magic link and password available
– Optional Magic Link – Password default, magic link alternative

5. Click Save Changes

Step 4: Configure Email Settings

Email Subject Line:


Your login link for [sitename]

Email Body Template:


Hello [username],



Click the button below to log in to [sitename]:



[magic_link_button]



This link expires in [expiration_time] minutes.



If you didn't request this, you can safely ignore this email.



For security, never forward this email to anyone.

Available placeholders:
– [username] – User’s display name
– [sitename] – Your site name
– [magic_link_button] – Styled button with link
– [magic_link_url] – Plain URL
– [expiration_time] – Token expiration minutes
– [user_email] – User’s email address
– [ip_address] – Login request IP
– [browser] – Browser information

Styling Tips:
– Use your brand colors for button
– Include logo in email header
– Keep text concise and clear
– Add security reminder

Step 5: Role-Based Configuration

Configure which user roles can use magic links:

Typical Configuration:
– ✅ Subscribers – Yes (blog readers)
– ✅ Customers – Yes (WooCommerce)
– ✅ Members – Yes (membership sites)
– ⚠️ Authors – Optional (consider security needs)
– ⚠️ Editors – Optional
– ❌ Administrators – No (use stronger authentication)

Why restrict admin access?
– Admins have elevated privileges
– Consider 2FA or password + magic link for admins
– Additional security layer justified for high-privilege accounts

Step 6: WooCommerce Integration (If Applicable)

If you’re running WooCommerce:

1. Go to Magic Link Login for WordPress → WooCommerce
2. Enable Checkout Magic Link
3. Configure checkout flow:
– Guest Checkout: Offer magic link for order tracking
– Account Creation: Auto-send magic link after purchase
– My Account Page: Replace password login with magic link

4. Set custom redirect after login:
– Shop page – For general customers
– My Account – Default
– Cart – If user was checking out
– Custom URL – Specific landing page

Step 7: Customize Login Page

Make the magic link option prominent:

1. Go to Appearance → Customize → Login Page
2. Update login page heading: “Enter your email to log in”
3. Adjust button text: “Send Login Link” (instead of generic “Login”)
4. Add help text: “We’ll email you a secure login link”
5. Hide password field (if magic link only mode)

Login page elements:


┌─────────────────────────────────┐
│     [Your Logo]                 │
│                                 │
│  Enter your email to log in     │
│  ┌───────────────────────────┐  │
│  │ Email Address             │  │
│  └───────────────────────────┘  │
│  ┌───────────────────────────┐  │
│  │   Send Login Link         │  │
│  └───────────────────────────┘  │
│                                 │
│  We'll email you a secure link  │
│  that expires in 15 minutes.    │
└─────────────────────────────────┘

Step 8: Test Thoroughly

Test Checklist:

☐ Basic Flow
– Enter email address
– Receive email within 30 seconds
– Click magic link
– Successfully logged in
– Redirected to correct page

☐ Token Expiration
– Request magic link
– Wait for expiration time
– Attempt to use expired link
– Verify rejection message

☐ One-Time Use
– Use magic link to log in
– Try using same link again
– Verify link is invalidated

☐ Role-Based Access
– Test with different user roles
– Verify correct users have magic link option
– Confirm admins don’t see it (if restricted)

☐ Email Delivery
– Test from multiple email providers (Gmail, Outlook, etc.)
– Check spam folders
– Verify formatting in different email clients

☐ Mobile Devices
– Test on iPhone
– Test on Android
– Verify one-tap login from email app

☐ Error Handling
– Test with non-existent email
– Test with invalid token
– Verify error messages are user-friendly

Step 9: Optimize Email Delivery

Poor email delivery ruins passwordless login. Ensure reliability:

Install SMTP Plugin:
1. Install WP Mail SMTP or Post SMTP
2. Configure with real SMTP service:
– SendGrid (free tier: 100 emails/day)
– Mailgun (free tier: 5,000 emails/month)
– Amazon SES (very cheap: $0.10 per 1,000 emails)
– Gmail SMTP (works but has limits)

Configure SPF Record:


v=spf1 include:_spf.google.com ~all

(Adjust for your email provider)

Enable DKIM Signing:
– Adds cryptographic signature to emails
– Proves email came from your domain
– Significantly improves deliverability

Set DMARC Policy:


v=DMARC1; p=none; rua=mailto:[email protected]

Test Email Delivery:
– Use Mail-Tester.com
– Aim for 9/10 or higher score
– Fix any issues identified

Step 10: Monitor and Optimize

After launch, monitor key metrics:

Track These Metrics:
– Magic link request volume
– Email delivery success rate
– Token usage rate (how many requested links are actually used)
– Time from email send to link click
– Support tickets related to login

Optimization Opportunities:
– If token usage 5 minutes, consider extending expiration
– Monitor abandoned login attempts

Step-by-Step: Custom Code Implementation

For developers wanting full control:

Step 1: Create Plugin Structure

php
<?php
/*
  Plugin Name: Custom Passwordless Login
  Description: Magic link authentication
  Version: 1.0.0
 /


// Prevent direct access
if (!defined('ABSPATH')) exit;



class CustomPasswordlessLogin {
    public function __construct() {
        add_action('login_form', [$this, 'add_magic_link_field']);
        add_action('wp_ajax_nopriv_request_magic_link', [$this, 'handle_magic_link_request']);
        add_action('wp_ajax_nopriv_verify_magic_link', [$this, 'handle_magic_link_verification']);
    }
    
    // Implementation continues...
}



new CustomPasswordlessLogin();

Step 2: Generate Secure Token

php
public function generate_magic_token($user_id) {
    // Generate cryptographically secure token
    $token = bin2hex(random_bytes(32));
    $expiry = time() + (15  60); // 15 minutes
    
    // Store token (hashed)
    update_user_meta($user_id, 'magic_link_token', password_hash($token, PASSWORD_DEFAULT));
    update_user_meta($user_id, 'magic_link_expiry', $expiry);
    update_user_meta($user_id, 'magic_link_used', false);
    
    return $token;
}

Step 3: Send Email

php
public function send_magic_link($user_id, $token) {
    $user = get_user_by('id', $user_id);
    $magic_url = add_query_arg([
        'action' => 'verify_magic_link',
        'token' => $token,
        'user' => $user_id
    ], wp_login_url());
    
    $subject = sprintf('Login link for %s', get_bloginfo('name'));
    $message = sprintf(
        "Hello %s,\n\nClick here to log in:\n%s\n\nThis link expires in 15 minutes.",
        $user->display_name,
        $magic_url
    );
    
    wp_mail($user->user_email, $subject, $message);
}

Step 4: Verify Token

php
public function verify_magic_token($user_id, $token) {
    $stored_hash = get_user_meta($user_id, 'magic_link_token', true);
    $expiry = get_user_meta($user_id, 'magic_link_expiry', true);
    $used = get_user_meta($user_id, 'magic_link_used', true);
    
    // Check expiration
    if (time() > $expiry) {
        return new WP_Error('expired', 'Magic link has expired');
    }
    
    // Check if already used
    if ($used) {
        return new WP_Error('used', 'Magic link already used');
    }
    
    // Verify token
    if (!password_verify($token, $stored_hash)) {
        return new WP_Error('invalid', 'Invalid magic link');
    }
    
    // Mark as used
    update_user_meta($user_id, 'magic_link_used', true);
    
    return true;
}
