Are there any way on how to add or CRUD multiple users in firebase(authentication) without the firebase admin sdk?

I do have this add user function in my web, however after of some research and google-ing, I found at that it needs to have a firebase admin sdk. Is firebase admin sdk is really necessary for doing this functions and are there any payment/billing when using it? Thanks

Any suggestions are appreciated

It sounds like you want to create multiple users, which is considered an administrative operation. While you could do this with a client-side SDK (as shown in Firebase kicks out current user), the recommended, idiomatic approach is to use a Firebase Admin SDK for this in a trusted environment (such as your development machine, a server that you control, or Cloud Functions/Cloud Run).

There is no cost to using the Admin SDK, as otherwise that would be indicated on the Firebase pricing page.

  • Hi Puff, I am trying the one that you've linked ``Firebase kicks out current user`` and it always says that ``secondaryApp.auth()`` is not a function, I've tried doing what he did on it. I think I might not need the firebase-admin-sdk since all the ``createUsers`` are the only thing I need. Thanks – flutternewbiee Mar 15 '23 at 07:25
  • As discussed in that answer, using the Admin SDK is the recommended approach these days. But if you're having a hard time making your code work, I recommend opening anew question with a [minimal repro](http://stackoverflow.com/help/mcve) of where you got stuck when you tried to apply the approach with a secondary app. – Frank van Puffelen Mar 15 '23 at 13:52
