I have authentication signup form on my app, which goes through firebase as expected and works fine. If i wanted to add another layer account authentication, what would you suggest?
Currently i have added the phone sms option in firebase as another signup method. so when they create a new account it will create the account and then go to a "add mobile number" screen which then goes to the "enter code" screen.
Is this the right way to do this? I can see that in the database, not only does it create the account from the signup form but also adds the record of the phone separately. should these authentication be as one so the telephone is synced to the account.
If anyone knows a better way, please let me know.
