Your app needs to know the identity of a user, in order to securely gate access to their data, and provide the same personalized experience across all of the user’s devices.

Crossmint Auth provides backend services, easy-to-use SDKs, and ready-made UI libraries to authenticate users to your app. It supports passwords, phone numbers, OAuth and more.

Crossmint Auth is fast to integrate, secure, and it leverages industry standards like OAuth 2.0 and OpenID Connect, so it can be easily integrated with your custom backend.

Key Characteristics

How Does it Work?

Crossmint Auth is a combination of two products: a user database, and APIs to authenticate and authorize those users.

To use Crossmint Auth, you first configure what sign-in methods you want to allow in your app, such as email and OAuth. Then, you either take Crossmint Auth’s UI components, or build your own auth UI. Finally, you call the user management APIs from your app front-end or back-end to access your user data.

Crossmint securely stores all your user credentials in an encrypted credential database, and implements industry best practices to securely authenticate and authorize your users.
