Hi, My app allows users to sign up/Login with facebook or google. My problem is that if the user signs up with facebook and email is David@gmail.com and then signs up with google and email is also David@gmail.com then it creates a separate account with the same email. how can i keep a user from signing up twice with the same email?
Are you sure? both accounts should be merged. Email us if not.
What if my Google email address is me@gmail.com and the Facebook email is me@facebook.com? Is there any way of preventing duplicate accounts?
Then adding another fly in the ointment, what if 6 months later I try to log on and forgot that I used either Google or Facebook? So I try me@someotherdomain.com and I am not found. What is the smooth way of handling any scenario of multiple email addresses?
If the user is logged in when he authenticates with a new service, accounts are merged. But if he’s logged out, there is no way for anyone to know that yourname@google.com is the same person as yourname@facebook.com.
So if the user started with a Bubble login, then later added a Facebook authentication, the accounts will be merged. What email address will that merged account show?
The email one, since it’ll be the primary email.
A condition can be made if user@gmail.com and user@facebook.com use the same password, correct? What are the chance of that too…
No, because passwords are hashed for security purposes. Comparing on passwords means they’d be public…
