#### Join Developers Using MagicAuth + rCAPTCHA

The perfect combination: passwordless authentication + bot protection for paid login flows

Users click a link in their email. That's it. No password resets, no "forgot password" emails, no weak passwords to worry about. Just instant, secure access.

rCAPTCHA verifies users before they can request a magic link, blocking bots and spam while keeping the experience smooth for real users.

MagicAuth is a paid authentication service. There are no developer payouts, credits, or custom earnings attached to login usage.

Use the free tier to test, then select Starter, Growth, Business, or Enterprise for production applications.
