About
A developer tool for projects using the Firebase Auth Emulator. Open the popup, search your emulator users, and click one to sign in as them — instantly and without touching your app's code. How it works: • Lists all users from your local Firebase Auth Emulator • Forges a custom token (the emulator skips signature validation) and exchanges it for a real ID token • Writes the auth state directly into your app's IndexedDB and reloads the page Setup: Open the extension settings and enter your emulator host, port, project ID, and Firebase API key. That's it. Note: This extension only works with the Firebase Auth Emulator on localhost. It is not intended for use with production Firebase projects.
