Issue with Google social login

Our app has a Google social login as well as App specific login.

When we register into the app using App specific registration, user enters the Email ID during registration. Once registered, their Email ID is stored in the Users system table. While trying to login using Google social login using the same Email ID, it mentions that User already exists in google login windows and doesn’t log into the app post this step.

Please suggest as to how to handle it.

Error code - 3003

Hi Harish,

Backendless currently doesn’t allow to have the same user be able to log in using a simple way and any social login at the same time.

That means, when you try to log in using Google+ for the first time, the registration process in launched, and thus you receive this error.

So you should have the user logging in either always using Google+, or always using simple login, but not both.

Hi, Harish!
In the upcoming release we’ll add fix for this issue - if user is registered in with an app specific registration he will be able to login with Google+ or Facebook profiles that have the same email address. Actually it can be any identity (e.g. social ID) - depends on what column you specify as identity.
