Adds Auth0 authentication to native Android apps with Web Auth, biometric login, and MFA support. The skill walks you through installing the com.auth0.android:auth0 SDK, fetches the latest version from GitHub automatically, and sets up login/logout flows with proper credential storage. It checks for existing UI handlers before creating new buttons, which is nice if you already have a sign-in screen. One thing worth noting: it includes a build verification loop that will try to fix compilation errors up to five times before asking if you want to continue, so you're not left with broken code. Best for Kotlin or Java projects on API 21+, not React Native or Flutter.
