Check if an user already exists
I'm using OTP based login in my app. I want to check if an user already has an account. If he/she doesn't have an account, their data will get uploaded to the database.
Is there any way to check if an user already exists in OTP based Phone authentication?
account.createPhoneSession() creates a new session for the existing user but doesn't throw error if user already exists.
TL;DR
Developers seeking to check if a user already exists in OTP based Phone authentication can utilize the method ```account.createPhoneSession()```. This function creates a new session for existing users, but it doesn't throw an error if the user already exists.
