Google Identity Toolkit: Link Multiple Accounts?

Question

I am looking for an "auth as a service" provider for my site, which allows my users to register using google / facebook and / or their own username / password. The problem is that I cannot find out if the Google Identity Toolkit will automatically merge accounts if the user uses the same email address for their facebook and google accounts. In addition, does the Google Identity Toolkit support password forgetting for user / password authorization?

Answer 1

Yes, the Identity Toolkit will automatically merge accounts based on email address. In some cases, the Identity Toolkit will need to ask the user for their previous credentials before performing the merge. For example, if a user has previously signed up with an email / password and then signed up with Facebook, they will be asked to enter the password for the last time.

Identity Toolkit will also help you send reset passwords. Here is the documentation to enable this feature and implemented in this sample .
