How It Works
Three steps. That's it.

No servers to configure. No SMS gateways to wrangle. Just embed, init, and verify.

STEP 01
Embed the script
Add a single <script> tag to your page. Works on any site — WordPress, React, static HTML, you name it.
STEP 02
Configure your AppCode
Choose your delivery method (SMS, WhatsApp, email, voice), set retry limits, and whitelist your domain.
STEP 03
Verify & go
Users receive a one-time passcode, enter it, and you get a verified token. Authentication done.
