Authentication screens

Recommended: JavaScript SDK with React Hooks

For new React apps, we recommend the JavaScript SDK with React Hooks (@dynamic-labs-sdk/react-hooks) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the React quickstart (JavaScript SDK) to get started.

Step-up authentication and device registration are required for all headless integrations. Without these, users will be blocked during login or sensitive actions. See the 2026_04_01 upgrade guide.

Implement the screens below based on which authentication methods you’ve enabled in your dashboard. Email is enabled by default for most projects.
