Quick Fix: The Kotlin Multiplatform OpenID Connect Support library, available at https://github.com/kalinjul/kotlin-multiplatform-oidc, provides OAuth2 authentication for KMM iOS and Android.

The Solutions:

Solution 1: kotlin-multiplatform-oidc library

The "kotlin-multiplatform-oidc" library provides a solution for OAuth2 authentication in Kotlin Multiplatform Mobile applications. It supports Authorization Code Flow and can be used in both iOS and Android applications. The library leverages platform-specific features like ASWebAuthenticationSession and Chrome Custom Tabs for authentication, abstracting away the platform-specific code required in your app.

To use the library, you can add it to your project as a dependency and use the provided factory to abstract the login process. This minimizes the amount of platform-specific code you need to write.

However, it’s important to note that the library is in an early stage of development and has not been tested against many IDPs.
