Magic Link Authentication

Passwords Are So 2019

Passwordless login smoother than a backcountry ski run on Loveland Pass

The "I Forgot My Password" Epidemic

True story from Pearl Street Parking: Their mobile app had a 67% login abandonment rate. Users would rather circle downtown for 20 minutes than reset their password. Not exactly the user experience they were going for.

Megan from LookoutLogistics fixed this:

"We switched to magic links for our delivery drivers. Login time went from 45 seconds to 8 seconds. Driver happiness up, delivery times down, customers happy. Win-win-win."

Magic Links That Actually Feel Magical

1. Enter Email

Quick email input

2. Check Email

Instant delivery

3. Click Link

One-tap access

4. You're In!

That's the magic

Implementation So Easy, It Feels Like Cheating

Step 1: Enable Magic Links (2 minutes)

// In your login component
const handleMagicLogin = async (email) => {
  const result = await api.post('/auth/magic-link', {
    email,
    redirect_url: window.location.origin + '/dashboard'
  });
  
  showMessage("Check your email for a magic link!");
};

Step 2: Handle the Magic (Automatic)

// Our SDK handles link validation automatically
import { MagicLinkHandler } from '@23blocks/auth-sdk';

// In your app startup
MagicLinkHandler.setup({
  onSuccess: (user) => {
    // User is logged in, redirect to app
    navigate('/dashboard');
  },
  onError: (error) => {
    // Handle expired/invalid links
    showError("Link expired. Please try again.");
  }
});

Step 3: Customize Everything (Optional)

// Advanced magic link options
const customLink = await auth.createMagicLink({
  email: user.email,
  template: "custom-login-email",
  metadata: {
    login_source: "mobile_app",
    feature_access: "premium"
  },
  restrictions: {
    device_type: "mobile",
    max_uses: 1,
    expires_in: "10m"
  }
});

Ready to Make Login Magical?

Stop losing users to password fatigue. Start delighting them with one-click access that just works.

P.S. We named our magic link system "Powder Pass" – both get you instant access to what you want without the usual hassle. Unlike lift tickets, our magic links never get lost in your jacket pocket.

P.P.S. We've delivered over 50 million magic links. That's more than the number of "Free Tibet" stickers on Subarus in Boulder. (Okay, maybe not quite that many.)
