Is there an easy way to delete all registered users from firebase console? For example, I created a hundred users from my development environment, and now I want to delete all of them.

We just released the Firebase Admin SDK, which supports administrative use-cases, such as deleting a user account without requiring that user to sign in first.

original answer

There is currently no API in Firebase Authentication to delete a user without requiring that user to sign in. We know this limits the usability of our API and are working to add such functionality in a future release. But as usual, we don't provide specific timelines for when the feature will be available.

For the moment your only work arounds are to:

• sign in as each test user in the app and delete the user from there
• delete each user in turn from the Firebase Console
