Introduction

How-to

Currently there are two ways of integrating World ID in external applications:

• IDKit libraries: Our lightweight SDKs that make it easy verifying users in your applications.
• Sign with World ID: Our OIDC implementation that integrates World ID into OIDC

Which should I use?

Choose IDKit if you:

• Want full control over the user interface
• Need to verify users without page redirects
• Want the quickest setup
• Want to uniquely verify your existing users too

Choose Sign with World ID if you:

• Already use OAuth/OIDC providers (Google, GitHub)
• Want a standard authentication flow
