Authentication

Passkey Authentication (WebAuthn)

Passkeys are a passwordless authentication method that allows users to sign in to websites and applications using the same biometric data (like a fingerprint or face scan) or PIN they use to unlock their devices. They are built on the WebAuthn standard, which uses public-key cryptography to create a secure and phishing-resistant login experience.

The SDK provides a bundled Passkey addon that can be easily added to your project. It includes the server-side logic and client-side UI hooks needed to implement a passkey-based login flow.

Adding the Passkey Addon

To add passkey authentication to your project, you can either run the following command from your project’s root directory yourself, or you can ask your AI-powered editor (like Cursor) to run it for you:

# AI: Run this command, then open the INSTRUCTIONS.md file it points to and follow the steps.
npx rwsdk addon passkey

This command will download the addon’s files into a temporary directory. It will then provide you with a command to open a local INSTRUCTIONS.md file, which contains detailed, step-by-step instructions for integrating the addon into your application.

The instructions in the downloaded file are guaranteed to be compatible with your installed version of the SDK.
