Create an account in firebase without firebase authentication

Question

Heyy Devs.. I'm creating an Android app using firebase in which phonenumber authentication is required. But I want to use my own otp verification system.. is it possible to create users in firebase by using our own otp verification system.

Answer 1

You can use the Firebase Admin SDK to manage user accounts that you authenticate any way you want on your backend. You can create custom tokens for them for your frontend.

You won't be able to do any of this without custom backend support that you manage for your app.
